UFOs: The Research, the Evidence

Status
Not open for further replies.
Very true. Planes crash because of mechanical failure or human error besides a natural disaster like been struck by lightning for example. Either way besides the natural explanation, it's human error either in the cockpit or in the manufacture of the craft in most cases.
 
The principals in the Tehran UFO incident

Sighting Date: September 19th 1976.
Location: Area surrounding Tehran city, Iran

First hand witness accounts

Houssain Pirouzi, tower controller, Mehrabad airport (source: interview by John Checkley via MUFON)
(http://www.mufon.com/famous_cases/1976 Iran Part 1 MUFON Case File.pdf)
Pirouzi received calls from 4 civilians reporting UFOs.
He looks northeast for a UFO and sees it through binoculars.
He describes it as cylindrical and bright and flashing blue, orange, red and yellow (in cycle) and it then changing its shape to resemble a “starfish”.
Pirouzi also describes the UFO as moving towards the north, very, very slowly and then “Suddenly, it appeared at another position one mile further on.”
Then 4 civilian planes began reporting an emergency distress signal (BOAC, Swissair, Lufthansa and Iranian Airlines).
General Yousefi (the “senior officer responsible on duty”) was called by a duty officer and the General called Pirouzi back.
Pirouzi reports that the General also saw the UFO “from the porch of his house” and then ordered an F-4 from “Hamadan” (Hamadan is the town and Shahrokhi airbase is about 20miles NNE of Hamadan) into the air.
(UFO now at 15000 feet to the NE of Tehran).
Pirouzi “I was getting instruction from Gen. Yousefi and passing them on to the pilot”. Thus we can assume Pirouzi was passing on information from the F-4 to the General.
The F-4 reports reaching Mach 2 but cannot catch the UFO.
Both UFO and F-4 were now “heading toward the border with Afghanistan” so Pirouzi orders the jet to turn back. He does so.
However, the UFO “had beaten him back” and was now again in front of the F-4 over Tehran!
The pilot reported that “every time he came close to the object, it affected his radio and all his instruments” (including “navigation aids”). He also reported receiving “some emergency signals”.
The pilot reports his fuel is now running short and will have to return to base.
UFO now 15 miles from Mehrabad tower at about 12000 feet.
A second F-4 had already been sent up and the pilot (we now know was squadron leader, Major Jafari) called the second plane “You go back to base … I’ll follow the object”.
This means of course that the second F-4 pilot (Jafari) KNEW what was happening to the first (a critical point).
Second F-4 is still 100 miles from UFO at this time.
General Yousefi orders Jafari to orbit at 15000 feet.
Jafari reports UFO “keeps changing position very fast indeed. I cannot follow the path of the object … he appears here, suddenly he appears there, and I can’t track him”.
Priouzi reports “We could all see the object with the naked eye” (there were others in the tower with him).
Jafari reports the object now “… divided into two and an illuminated object has separated and is following me.”
Jafari flies over Mehrabad tower and Pirouzi reports seeing this second light, for the first time “500 feet above and just behind him”.
Jafari reports the second object now “rejoins” the first and “They now appear to be discussing together”.
UFO and second object now (according to Pirouzi) about 15 miles from the tower.
Jafari then reports “Now they have joined together”.
Jafari decides to return to base because it was “too dangerous to go any closer” because “every time he got close, his navigation and electronics systems went crazy”.
Jafari then reports that the object has again split in two and “the illuminated” part has “settled on the ground” (according to Pirouzi) to the southeast of Tehran “near a place called Rey”.
Interestingly Pirouzi denies that Jafari tried to fire on the UFO.
According to Checkley “The air traffic controller made his report to Air Force headquarters the next day, in which he reported full details of the arial battle of wits, including the fact that both pilots reported their navigation aids and their missile-firing equipment both went out of action when they got close to the UFO.”

NOTE: Interestingly I discovered a video of a UFO from Brazil (30 Dec 1990) that looks almost exactly like the droopy starfish shape Pirouzi describes (and draws) (http://www.dailymotion.com/video/x5t3s0_ovni-a-niteroi-bresil-30dec-1992_tech). Now here is a repeat of a UFO of the same description! (and who said there were no discernible patterns to be found in the study of UFOs!).

NOTE: Brigadier General Abdullah Yousefi was senior officer in charge on the night and in direct phone contact with tower controller Pirouzi during the incident.

Major Parviz Jafari, pilot of the second F4 (source: Press club statement and interview) (http://www.youtube.com/watch?v=KJydT3AZ370) and (http://www.iranian.com/main/singlepage/2008/parviz-jafari-2)

There also exists a highly detailed moment to moment account by Jafari in an (as yet unpublished) forthcoming book by Leslie Kean [Random House] (source: The Paracast 18th Oct. 2009, 19:38) (http://www.theparacast.com/show-archives/)

Jafari confirms the substance of what Pirouzi reports but adds details – including the claim that he DID try to fire on the UFO but that his missile systems failed when he did this. This may seem inconsistent but Pirouzi is actually CORRECT in that a missile was NOT fired. Pirouzi’s language in his denial is also VERY interesting. He stated that “The pilot did not try to fire on it” (italics added). Now WHY would he have stated “try”? - unless he actually knew that a failed attempt HAD been made! Otherwise he would simply have stated that the pilot “did not fire” on the UFO. And besides, why even mention the (attempted) missile firing thing if he was not being defensive? Thus the seeming inconsistency here IS explicable; Pirouzi WAS being defensive (probably not knowing if Jafari had reported the incident in HIS “debriefing”).

Henry & Bob, avionics engineers (source: interview by Dr Bruce Maccabee)
(http://www.brumac.8k.com/IranJetCase/) Maccabee reports (“When I talked to Henry in late 1982…”) “Several days after that, he and co-workers were allowed to examine the planes. They found that all the electronics were operating normally. This was surprising, considering what the pilots reported had happened during the chase!”

Accrding to Maccabee “Henry was a Westinghouse Corporation avionics engineer stationed at Shaharoki AFB where he participated with the IIAF in maintaining the operation of the radar and other electronics in the F-4 jets.”

“The same thing happened at Mehrebad where the second jet landed. Bob, another Westinghouse avionics engineer, was not allowed to examine the jet for several days after the incident. However, the Iranians did examine it during the day after it landed and subsequently told him that everything was OK. Four days after the incident Henry was allowed to examine the first jet and Bob was allowed to examine the second jet. They could find no problem with the avionics or radar. Henry told me that there was no possibility that the Iranians had switched radar systems (taken out the system used during the chase and replaced it with another system) because the Westinghouse engineers had kept track of the system serial numbers. The serial numbers were all the same. Hence the Westinghouse engineers had to agree with the Iranians that the jet chase had occurred, apparently with “self-repairing” failures of the avionics on two jets when in the vicinity of the UFO. Bob told me that he had worked on radar systems such as on the F-4 for many years and had never had a self-repairing failure such as reported by the Iranian pilots.”

Second hand accounts

General Abdullah Azarbarzin deputy operations commander in chief of the imperial Iranian Air Force (source: John Cathcart via MUFON)
(http://www.mufon.com/famous_cases/1976 Iran Part 1 MUFON Case File.pdf)

Confirms the story and adds details such as:

“Q: Is it true that they were unable to fire their missile?
A: No, they could not because they had very strong jamming.
Q: Jamming – some jamming you obviously couldn’t find a reason for?
A: No we couldn’t because that happened to both of them – and one airliner, which was flying in the area at the time.
Q: Right. The equipment on the airliner was also jammed?
A: Well, yes, it was jammed. Of course, they only had radio.”

So he too is under the impression that (at least one) pilot tried to fire on the UFO but “could not because they had very strong jamming”.

Lieutenant Colonel Olin Mooy (Memorandum for the Record) (MUFON via FOI requests)(http://www.mufon.com/famous_cases/1976 Iran Part 1 MUFON Case File.pdf)

Mooy was invited to sit in on the interview with the pilot of the second F-4 major Jafari. Thus he had a firsthand account from which to draw information from and also General Yousefi states:

“Q: Are you planning g to take further action?
A: No, no, we do not but we have - - all we have done we have given all the information - - of course that was the request from U.S. We have given all this information to our MAAG. I think they send it to the organisation in the Sates and - - we haven’t done anything since that time.”

Meaning of course that he (or the Iranian intelligence) passed ALL the information they had onto Mooy (who WAS the MAAG representative in Iran at the time)! So Mooy had ALL the pertinent information about the case from which he then constructed the Memorandum for the Record. Mooy then obviously passed this memorandum to Colonel Frank B. McKenzie.

NOTE: The Memorandum for he Record is ESSENTIAL reading for anyone who wants to understand the case.

Colonel Frank B. McKenzie, the defense attaché at the U.S. Embassy in Tehran at the time, with some minor editing, created what is now known as “The Routing Slip” (http://www.nsa.gov/public_info/_files/ufo/routing_slip_ufo_iran.pdf)
which is practically a word for word copy of Mooy’s memorandum.

The Routing Slip was sent to various US agencies including the DIA where Air Force Major Roland B. Evans (who was then stationed at Offutt Air Force Base in Omaha, Nebraska) wrote an “assessment” of the Routing Slip for the DIA. Evans, in his professional capacity, concluded that the information it contained was “reliable” (confirmed by other sources) and of “high” value as “current intelligence”. Also that the “credibility” of the witnesses was high” and that the visual sightings were “confirmed by radar”.

According to Bob Pratt (a National Enquirer reporter) who interviewed Evans (“I phoned Major Evans in January 1979”), “I was an intelligence analyst," said Major Evans. "This (Iran incident) came through as a routine intelligence analysis. I was given the report because my field is electronic warfare. The DIA intelligence community is broken up by region. Within each region we have some specialties. I was in the Middle East region and I was an air defense expert. I was given this particular case because of my electronic warfare and air defense field.”

“This was a classic case because everything that was bizarre about it was confirmed with real sources," he told me. "We don't have this capability to jam all these systems simultaneously.”

In his evaluation of the Tehran case, filed October 12, 1976, and approved by a civilian superior, Clifford J. Souther, Major Evans stated:

"An outstanding report! This case is a classic which meets all the criteria necessary for a valid study of the UFO phenomenon:

"(a) The object was seen by multiple witnesses from different locations (i.e. Shemiran, Mehrabad, and the dry lake bed) and viewpoints (both) airborne and from the ground.

"(b) The credibility of many of the witnesses was high (an air force general, qualified aircrews and experienced tower operators)

"(c) Visual sightings were confirmed by radar.

"(d) Similar electromagnetic effects (EME) were reported by three separate aircraft.

"(e) There were physiological effects in some crew members (i.e., loss of night vision due to the brightness of the object).

"(f) An inordinate amount of maneuverability was displayed by the UFOs.”

The UFO's ability to jam several systems simultaneously greatly impressed Major Evans, who said this was the only UFO case he had evaluated in his four years with the DIA.

"We had several other messages that someone would attribute to UFOs," said Major Evans. "I didn't pay much attention to them, but I felt this particular case was very interesting. Here we had a case where we had a visual sighting from three different locations, three different angles, by highly qualified people and they were confirmed by radar from three different points.

"The electromagnetic effects were very interesting to me as an electronic warfare officer, and the fact that this thing was so highly manoeuvrable impressed me quite a bit. As an electronic warfare officer, I would love to go into combat with the capability of turning off my opponent's weapon system panel at will, and to be able to figure out when he's going to turn it on, and to cut off his communications. (http://www.cohenufo.org/iran.htm)

The above then represents the principle witnesses and documents in the case. The above also represents the substantive FACTS of the case. ALL other representations of the case are derived principally from the above sources.

There are of course other researchers involved (like Klass) and documents that are secondary to the case (like newspaper reports, most of which may be accessed at (http://www.mufon.com/famous_cases/1976 Iran Part 1 MUFON Case File.pdf) and finally there was also the Now you see it article by Captain Henry S. Shields, ASAFE/INOMP) (http://www.nsa.gov/public_info/_files/ufo/now_you_see.pdf) which can also be found in its original context (in the USAF Security Service MIJI Quarterly Journal) at the MUFON case file site (as already cited above (http://www.mufon.com/famous_cases/1976 Iran Part 1 MUFON Case File.pdf).

Now that we have the principle sources sorted out we can investigate questions about the case more coherently.

Roger, your own source (from Block 42 ....) shows the AN/APQ-120 as the multi-purpose radar set of the F4-E. This was a necessary change because due to the inside 20mm cannon in the nose was not enough space for the bigger radar sets of the F4-C/D.
Do you own a radio or tv-set? Can they broadcast? No, they can't because they are receivers only for radio and tv transmissions.
The same is valid for the APR-36/37 - it's a receiver only to warn against radar emissions of enemy radars. The acoustic warning tells the pilot something bad is happening (like a missile is on the way to him), the display shows the direction of the threat (which direction is the enemy radar transmitter located).
If this description is not good enough for you, then i can't help you.

No.. But I thank you for the description. I truly DO appreciate someone at least attempting to answer legitimate questions from me! So thank you gambling cruiser for taking the time to do so.

The other question I had was: What WAS the actual RADAR set installed in the F-4 then if it was different to the APR-36/37? According to all your explanations the MUST have been a separate system... so what was it?
 
Oh...I agree. However, the story as it stands now is that we had a pilot who was either an experienced Major/Lt Col. and possibly the squadron commander OR just a LT. We do not even know if Jafari's training had included some night flying/intercept operations.

In either case, pilots can, and do, make mistakes that include errors in judgement, failure to operate their craft properly causing malfunctions, and misperceptions. I could list dozens of civilian and military aircraft pilots with plenty of experience making these errors. This includes pursuing UFOs that turned out to be stars (I can think of three cases at the moment). Instead of accepting the possibility that Jafari erred and/or that the aircraft may have had some malfunctioning avionics, we are told that the UFO influenced the aircraft. No big surprise here.

Astrophotographer: According to the evidence Jafari was a squadron leader and a Major at the time of the incident and he retired as a General. It is unreasonable to suppose that he would simply lie about his military status when that information COULD be checked against his military record if one made an effort to do so. If he DID lie, then HE WOULD KNOW that the information COULD (relatively easily) be falsified and then his status and his story would be trashed. It simply beggars belief that Jafari would do such a thing. In other words there is NO reason for jafari to lie about his military record.

On the other hand there is every reason for YOU to attempt to "downgrade" his military record because "downgrading" is essential to support your claim of incompetence. In other words YOU have a reason to falsify the evidence, Jafari doesn't.

Simply, unless you can come up with anything to support your claims, Jafari must be considered to (have been) a competent pilot. There is NO real reason to consider otherwise.

You seem to imply that the F-4s on the night might have "chased stars" and that simply does NOT accord with the evidence in the case. It is QUITE obvious that SOMETHING highly mobile was in the sky over Tehran on the night in question and that F-4s were sent up to investigate.

We also have evidence that whenever the F-4s approached to within a certain distance of the UFO, their avionics were detrimentally affected. The affects on the F-4s avionics are not in question and we also have the first hand accounts of the avionics engineers that there was NO malfunction in the planes. Besides, there were THREE planes so affected on the night... including a civilian airliner!

Your claims are simply NOT reasonable in the face of the verified evidence Astrophotographer... but of course it is the ONLY thing you can cling onto in support of your own preconceived belief system. Simply your claims are NOT supported by the verified evidence in the case and you are merely attempting to rewrite history in support of your own preconceived belief system.
 
Simply, unless you can come up with anything to support your claims, [...]


Yeah, yeah. Unless you can come up with something to support your claim that aliens exist, something other than your arguments from ignorance and incredulity, all your blathering isn't serving your declared purpose of this thread.
 
The above also represents the substantive FACTS of the case.

Be careful what you define as a FACT. A FACT is something that absolutely can not be denied. It is a FACT that Pirouzi saw something strange. It is a FACT that the F-4s were sent to intercept an unknown. It is not a FACT that the UFO definitely affected the aircraft. It is not a FACT that the UFO was an alien spaceship or something exotic. These are all assumptions based on personal bias of what one wants to believe. Let me know when you have the radar tapes, the audio tapes from the tower in communication with the pilots, and the maintenance records of the aircraft.
 
According to this site, it was the AN/APG-30, fitted in the nose cone, later replaced by the APG-76 (http://www.globalsecurity.org/military/systems/aircraft/f-4e.htm).

It took me about 30 seconds googling to find that out.

Thank you wollery. Direct, pertinent information is ALWAYS helpful and I appreciate your supplying it.

Interestingly however, according to the site you reference it COULD have been the AN/ALR-46… but that IS nitpicking... ;)

However it is interesting to note that:

“The RWR usually has a visual display somewhere prominent in the cockpit (in some modern aircraft, in multiple locations in the cockpit) and also generates audible tones which feed into the pilot's (and perhaps RIO/co-pilot/GIB's in a multi-seat aircraft) headset. The visual display often takes the form of a circle, with symbols displaying the detected radars according to their direction relative to the current aircraft heading (i.e. a radar straight ahead displayed at the top of the circle, directly behind at the bottom, etc.). The distance from the center of the circle, depending on the type of unit, can represent the estimated distance from the generating radar, or to categorize the severity of threats to the aircraft, with tracking radars placed closer to the center than search radars.” (http://en.wikipedia.org/wiki/Radar_warning_receiver)

SO, the pilot (at least the backseater) CAN know if something is behind AND the distance as WELL! THAT is what I HAVE been contending all along!

The initial contention by Puddle Duck was that it would have been impossible for Jafari to have noted the DISTANCES that the object was closing from behind him. BOTH the AN/APR 36/37 OR the AN/ALR-46 had displays (as described above) and WERE then capable of providing distance estimates - which Jafari COULD have relayed to the tower!

So again (as I have claimed all along) Puddle Duck is proved incorrect! Huh!
 
Astrophotographer: According to the evidence Jafari was a squadron leader and a Major at the time of the incident and he retired as a General.

What evidence? So far, the evidence I have seen indicates he was a LT. at the time. Can you present his personnel file or the list of the personnel in the squadron at the time?

It is unreasonable to suppose that he would simply lie about his military status when that information COULD be checked against his military record if one made an effort to do so.

Who is going to bother? Obviously you are accepting it as factual. At least one of the sources you cite states he was a LT and the source provided by puddle duck agrees.

If he DID lie, then HE WOULD KNOW that the information COULD (relatively easily) be falsified and then his status and his story would be trashed. It simply beggars belief that Jafari would do such a thing. In other words there is NO reason for jafari to lie about his military record.

Really? What records exist pre-revolution in Iran? Most were probably destroyed and it is not beyond somebody to inflate their resume somewhat. Demonstrate with real evidence that he was a Major and the squadron commander. As I stated, there are multiple sources indicating he was just a LT.



You seem to imply that the F-4s on the night might have "chased stars" and that simply does NOT accord with the evidence in the case. It is QUITE obvious that SOMETHING highly mobile was in the sky over Tehran on the night in question and that F-4s were sent up to investigate.

Yes, we have heard this all before. No real proof that this was the case.


We also have evidence that whenever the F-4s approached to within a certain distance of the UFO, their avionics were detrimentally affected. The affects on the F-4s avionics are not in question and we also have the first hand accounts of the avionics engineers that there was NO malfunction in the planes. Besides, there were THREE planes so affected on the night... including a civilian airliner!

So we are told. However, you are drawing a conclusion based on belief and not on real evidence. We are told this was the case but where is the real proof? Where are the records from the IIAF?

Your claims are simply NOT reasonable in the face of the verified evidence Astrophotographer... but of course it is the ONLY thing you can cling onto in support of your own preconceived belief system. Simply your claims are NOT supported by the verified evidence in the case and you are merely attempting to rewrite history in support of your own preconceived belief system.

"verified" evidence? The evidence is conflicting. Pirouzi is contradicted by the General (Afghan border). Pirouzi is contradicted by the USAF report (he reports seeing the UFO over the F-4 as it passed over the airport - the report says the ATCs could not see this UFO). Jafari says he was a major but the stories circulated indicated he was just a LT. You then make the leap that the UFO HAD to affect the avionics. Nothing else could have caused the error. You accept the stories told by Maccabee by the engineers but reject the evidence provided by Klass from TR-1 and TR-2. Keep cherry picking.
 
SO, the pilot (at least the backseater) CAN know if something is behind AND the distance as WELL! THAT is what I HAVE been contending all along!

No. The distance being displayed has a lot to do with the signal strength of the transmitting radar. Are you stating the UFO was using a radar to track the F-4?
 
Exactly - the range information which the device could display could be derived from the received signal strength. So range information would depend on knowing the particular type (and therefore the radiated power) of the radar system used or weapon type homing in on the aircraft. An unknown radar source would not produce measurable range information.
 
Be careful what you define as a FACT. A FACT is something that absolutely can not be denied. It is a FACT that Pirouzi saw something strange. It is a FACT that the F-4s were sent to intercept an unknown. It is not a FACT that the UFO definitely affected the aircraft. It is not a FACT that the UFO was an alien spaceship or something exotic. These are all assumptions based on personal bias of what one wants to believe. Let me know when you have the radar tapes, the audio tapes from the tower in communication with the pilots, and the maintenance records of the aircraft.

Actually it is a FACT that whenever the F-4s approached the UFO within a certain distance their avionics were detrimentally affected. THAT is a FACT. The key is what we DO with that fact. Do we simply assign it to "coincidence - as you seem to want to do? That seems highly unlikely. According to the evidence it happened EVERY time the F-4s got close to the UFO and all was okay again when the F-4s traveled away from the UFO. It is like sticking your hand in a fire. You get burned (practically) every time - but you want to make a coincidence of that type of relationship!? If it did NOT happen EVERY time the jets approached the UFO then you MAY have a better case. But it occurred EVERY time!

I have only claimed (for this case) that the UFO exhibited intelligent control and exhibited capabilities beyond the technological capabilities of the time (and NOW as well).

I then claim that this supports my "alien" hypothesis (in that there was demonstrated intelligent control of the UFO and it had technological abilities we cannot match). Can YOU come up with a reasonable explanation that is in accord with the verified evidence of the case?

This is NOT a personal bias. It is a hypothetical based on the evidence presented in the case. In other words, the hypothesis FITS the evidence. On the other hand, you have come up with precisely NO alternative explanations that fit the evidence.

What would the radar tapes etc tell you that is not already on the record? We have FIRST HAND witness accounts that radar contact WAS made, we have FIRST HAND witness accounts of the tower conversations and we have FIRST HAND witness accounts of the planes' (avionics) maintenance status.

As you well know, all such "hard" evidence in military cases (especially) that you require invariably "disappears" into the black hole of the US "intelligence" machine - never to be released, even under FOIA requests. THAT is another FACT for you Astrophotographer. Of course the obvious question is then WHY don't they release such information? If as you contend there is nothing to these cases except witness misidentification etc, then WHAT is the POINT of withholding such evidence as radar tapes, tower conversations, etc? If it IS as you contend, then the information from such sources would support that contention... but it is not forthcoming. Suspicious? YOU BET!
 
No. The distance being displayed has a lot to do with the signal strength of the transmitting radar. Are you stating the UFO was using a radar to track the F-4?

So range information would depend on knowing the particular type (and therefore the radiated power) of the radar system used or weapon type homing in on the aircraft. An unknown radar source would not produce measurable range information.
The quote I provided clearly states that the DISTANCE is estimated from the distance of image the from the centre of the display. THAT has NOTHING to do with signal strength…

Again I repeat: Puddle Duck contended that it was impossible for an F-4 pilot to have estimated distances to an object behind him. I have demonstrated that it IS CLEARLY POSSIBLE to do so! THAT is my point and it is the ONLY claim I make about the matter. Simply Puddle Duck has AGAIN been proven wrong. When are you going to admit that FACT?
 
Actually it is a FACT that whenever the F-4s approached the UFO within a certain distance their avionics were detrimentally affected. THAT is a FACT.
No, its not. If it were, we would have substantial evidence for that. One would think that a 'scientist' would know the difference between knowing and assuming.

And even if it was true, it wouldn't indicate alien tech, even EW systems from that day can really mess around.


What would the radar tapes etc tell you that is not already on the record? We have FIRST HAND witness accounts that radar contact WAS made, we have FIRST HAND witness accounts of the tower conversations and we have FIRST HAND witness accounts of the planes' (avionics) maintenance status.
Your accounts are little more then hearsay.


WHAT is the POINT of withholding such evidence as radar tapes, tower conversations, etc? If it IS as you contend, then the information from such sources would support that contention... but it is not forthcoming. Suspicious? YOU BET!
Lets see of possibilities:
- Too much work
- Pieces are already gone/disposed (room cost money)
- They may contain hints to classified procedures or other classified data.
 
The quote I provided clearly states that the DISTANCE is estimated from the distance of image the from the centre of the display. THAT has NOTHING to do with signal strength…
I'd really like you to provide your evidence that the position of the trace on the display has "nothing to do with signal strength". Really.
My suspicion is that it has everything to do with signal strength.

Again I repeat: Puddle Duck contended that it was impossible for an F-4 pilot to have estimated distances to an object behind him.
Again you twist what PD said to suit your purpose. Again, he said the crew had no means of measuring the range of the unknown object behind them, as they allegedly did in whichever document it was that contained what looked like (but probably wasn't) a partial transcript. This is still true.

THAT is my point and it is the ONLY claim I make about the matter. Simply Puddle Duck has AGAIN been proven wrong. When are you going to admit that FACT?

Unless you're willing to admit that this was not a UFO, but an aircraft with Soviet radar, you aren't going to be correct about this.

The distance on the display may well be inversely proportional to signal strength. But the display can only be calibrated in terms of distance, for an emitter of a single effective radiated power. I use ERP because it takes into account the effects of using a directional antenna. If the emitter is lower power, it will look further away on the display than the emitter used to calibrate it. If the emitter is higher power, it will look closer on the display.

Without a rear-facing emitter on the airplane, you can't get the round-trip time between the aircraft and the target.
Without that information, you can't get range information on an unknown target.

For threat information, though, a very approximate range and azimuth information as rough as which quadrant it is in is still very useful to the pilot. I'm sure the designers had a pretty good idea of the received signal strength necessary for a Soviet radar to lock on to a target. Once the threat is that close, it doesn't need to be any closer.

It seems that your lack of reading comprehension even affects your own posts?

It almost looks like that you seem to think that it is a magical box that automatically knows the distance to the radar source, then displays it. To use it that display to estimate the distance.

How do you think it derives distance before it is displayed?

So you take second or third or fourth hand sources over first hand sources then? I just posted above a list of all sources with verifiable provenance and you simply ignore it to cite sources that are NOT first hand. Your hypocrisy knows no bounds! Even Puddle Duck stated directly that he had NO reason to disbelieve Jafari - so you are simply (again) rewriting history to suit your own preconceived belief system.

I stated:

Yes, we have heard this all before. No real proof that this was the case.
And now you directly deny the evidence of the case! It never happened? Have you gone mad Astrophotographer. No-one to this point has claimed the case never happened! Now you do?

I stated:
We also have evidence that whenever the F-4s approached to within a certain distance of the UFO, their avionics were detrimentally affected. The affects on the F-4s avionics are not in question and we also have the first hand accounts of the avionics engineers that there was NO malfunction in the planes. Besides, there were THREE planes so affected on the night... including a civilian airliner!
So we are told. However, you are drawing a conclusion based on belief and not on real evidence. We are told this was the case but where is the real proof? Where are the records from the IIAF?
Where is the "real proof"? First hand eyewitness testimony means nothing at all to you? Pirouzi is a liar? Jafari is a liar? Henry and Bob are liars? Mooy is a liar? In fact, to support your perspective on the case practically everyone involved must be lying..! Do you even think about what you are writing any more Astrophotographer?

"verified" evidence? The evidence is conflicting. Pirouzi is contradicted by the General (Afghan border).
You are 100% wrong Astrophotographer!

Pirouzi ONLY stated that both the UFO and F-4 were "heading toward the border with Afghanistan". THAT is a DIRECTION, NOT A LOCATION.

Q: Apparently one of the fighter planes had to follow the UFO almost to the Afghanistan border?
General: “No, no, no, we didn't. This was only in the vicinity of Tehran..."

"Pirouzi is contradicted by the USAF report (he reports seeing the UFO over the F-4 as it passed over the airport - the report says the ATCs could not see this UFO).
Pirouzi: “I saw this light for the first time, though only for a few seconds.”

Memorandum for the Record: “During the time that the object passed over the F-4 the tower did not have a visual on it but picked it up after the pilot told them to look between the mountains and the refinery.”

THOSE are the FIRST HAND accounts Astrophotographer and there is NOTHING contradictory about them. You rely on second hand interpretations to make your spurious points! hypocrisy? YOU BET!

"Jafari says he was a major but the stories circulated indicated he was just a LT.
Again, WHY would Jafari lie? He has NO need to do so. Being a Lt. would NOT have made his story any less believable. Again you take second(third and fourth) hand accounts over first hand evidence. Hypocrisy? YOU BET!

"You then make the leap that the UFO HAD to affect the avionics. Nothing else could have caused the error.
No, I have stated my position a number of times now. Actually it is a FACT that whenever the F-4s approached the UFO within a certain distance their avionics were detrimentally affected. THAT is a FACT. The key is what we DO with that fact. Do we simply assign it to "coincidence - as you seem to want to do? That seems highly unlikely. According to the evidence it happened EVERY time the F-4s got close to the UFO and all was okay again when the F-4s traveled away from the UFO. It is like sticking your hand in a fire. You get burned (practically) every time - but you want to make a coincidence of that type of relationship!? If it did NOT happen EVERY time the jets approached the UFO then you MAY have a better case. But it occurred EVERY time!

"You accept the stories told by Maccabee by the engineers but reject the evidence provided by Klass from TR-1 and TR-2.
Are you calling Dr Maccabee a liar now too? “Real” evidence from Klass? WHAT “real evidence” from Klass?

Keep cherry picking.
OMG! Talk about the pot calling the kettle black! You are “unreal” Astrophotographer (notice I am trying really hard to be polite here). You will make ANY statement, despite the evidence… in the FACE of the evidence… Do you REALLY actually truly believe the utter nonsense you are writing now?
 
Ignore my statements if you like but I will keep repeating the FACTS. Puddle Duck contended that it was impossible for Jafari to have relayed distance information from an object behind him. I have CLEARLY DEMONSTRATED this to be a false proposition. When are you all going to admit that FACT?

I have made no claims on the matter outside the demonstration that the F-4 HAS the capability to determine distance information of an object behind it. THAT has been my ONLY contention ALL along and I HAVE been proved correct in that contention.
