No, that's not what I believe. I believe (and is also fact), .
If your beliefs define reality you must be god.

Question here ... Turbofan, are you getting your technical information from a salesman, and a set of specifications? Do I understand that correctly? Or are you yourself the salesman?
I'm honestly confused here. I have no pretense to technical knowledge -- though 1/ professionally, I know enough not to take the word of the sales guys on technical matters, and 2/ just from life, I am aware that just retyping specs doesn't mean much.
Please stop quoting regulations and L3's design specs on what happens when power is lost. Crashing into a wall is not the same as a power failure.
No, it doesn't. Just because something might be designed in a particular way doesn't mean it actually happened. I'm not saying you are wrong, just that you haven't proven anything. You are relying on how you believe it's designed (and making all sorts of misapplied assumptions in that, as well) and making no effort whatsoever to explain all the other evidence.
The animation's purpose isn't entirely known but it's known to contain numerous errors. It's certain that it wasn't made to be inch-accurate for forensic analysis.
Yes, you THINK radalt shows this. We understand. We aren't arguing about what the RADALT says (mostly because you've never made the necessary tools available to check your work). We are arguing about what the time slip error is. This is an issue that you people continuously skirt with your "appeal to regulation" and other nonsense. The best part of it all is that you cannot even do that properly.
If all you did was come here to repeat the same tired arguments and troll then I won't be around to talk about it much longer.
Feel free to present something I haven't heard at least 20 times.
It is stating that it very well could be corrupted
Which means that the contents will not be reduced to mush at as high as 3400 g's, not that 'write' will not screw up the last bit of memory at an impact of 3400 g's
Of course you completely ignore the fact that the equipment when through hundreds, or even thousands of take-offs and landings. Even though it could take a single 3400 G jolt, the stresses of normal use can take it's toll. When was the FDR certified? What is the schedule of re-certification? When was that FDR last serviced?Sorry, that is incorrect.
Crash protected memory states that the data is safe up to 3400 G's.
Check out the specifications to meet certification.
This means what ever is stored up until power is removed from the FDR
is kept safe.
P.S. For the person that asked why I have returned, it is because I now
have the chance to discuss this topic with Anti. I also posted information
pertaining to questions that I was asked to supply. I will not answer those
who are rude, or do not engage in topic related conversation.

Yes it worked/recoreded data just after impact.
http://www.ntsb.gov/info/foia_fri.htm
Here at the reading room at the NTSB you can get a copy of the readout, here.
http://www.ntsb.gov/info/UAL93FDR.pdf
The data files are on the web somewhere, not sure where I got 4 files of the FDR read out in excel readable files. If you need them they are out there, or I can email them if you have to have a copy.
The final altitude on 93 was 2189 feet pressure altitude. At Newark, the field is 18 feet, the pressure altitude at take off was –297. Add 315 to 2189, 2504 feet for last altitude stored. The field was 2400 feet. With a final speed of 487.5 knots, the plane moving at 812 feet per second means the FDR stopped recording data just after impact.
Last mag heading 187, pitch –41.1, bank 142.
This IS a very definite safety issue if the data stored on the DFDR is not reliable then something needs to be addressed and the sooner the better. DFDR data of crashes are used to determine the cause of crashes and what measures need to be taken to fix problems. This would not apply to Flt 77 as the plane was working just fine but it would apply to many other crash situations. Lives are at stake and those who believe that the DFDR data of Flt 77 is incorrect are busying themselves argueing about it on the internet rather than actually trying to do anything about it other than make bombastic phone inquiries to the NTSB. Where is the technical paper? Why has it not been submitted to the NYT, Aviation Weekly, Popular Science even? Why has it not been submitted to the NTSB, ICAO and the pilot's union, or Boeing and L3?
The Flight data record for 93 only stored 1/4 the data stored by 77.Forgive me Beachnut but if I read this correctly you are saying that the last recorded altitude was 2504 and the crash site is 2400 feet. That means that the last recorded altitude is 104 feet above the crash site and in that data frame of the DFDR it was doing 487.5 knots, banked at 142 deg and pitched down 41.1 deg. with a time to impact of approx 1/8th of a second.(approx 1/4 of the 500 ms spec that Turbofan quotes)
On another note I again ask why PfT and Calum Douglas and Rob Balsamo have not written up a technical report detailing the errors in the DFDR data as opposed to the accepted flight path of Flt 77 described by the bulk of witnesses and all the physical evidence.
This IS a very definite safety issue if the data stored on the DFDR is not reliable then something needs to be addressed ...
Perhaps TF would venture an answer to this. I do not expect him to know the thoughts of Douglas or Balsamo but would appreciate his thoughts on it.
What is the purpose of a FDR? Why is a tangent an electrical engineer and USAF Command Pilot interested in, have anything to do with the events of 9/11? Nothing!Sorry, that is incorrect.

Just the notion that a plan would be hashed just hoping that there would be a one in a million chance of no one seeing the plane fly over the Pentagon is hilarious.
Ok...I'm convinced or at least I almost was until I realized that you have this damning evidence that could convict so many people and honor the 3000 Americans that died on 9/11 yet you waste your time on here? What's your angle?Does anyone here actually look at the NTSB supplied CSV file?
