Could you explain your working hypothesis that might be balance of probabilities?
Apologies for the late reply, I've been busy emigrating to Germany. Also the HD that has all of my old Lockerbie research on it is in a box "somewhere over there" and I can't find it atm, so am writing all this off the top of my head, if I make any glaring errors here, please point them out and I will correct/update them when I can.
So, PT/35b What is it? When was it found? Where was it found? How does it connect to the bombing of PA103? Who does it implicate?
What is it?
It is a fragment of printed circuit board (PCB) about the size of a fingernail that bears unique circuit traces from which it can be identified. If genuine, it comes from a timing circuit (MST-13) that was manufactured by MeBo. A *huge* number of investigators and researchers, both at the time and subsequently have searched for matching PCBs that this fragment can be placed in and to date there is only one match. An MST-13.
When/Where was it found?
It was found by Dr Thomas Hayes, head of the Forensics Explosives Lab at RARDE on 12 May 1989, while he was examining evidence as part of the initial investigations. It was folded into a bomb damaged shirt fragment that as known to have been in close proximity to the bomb that brought down the flight. The shirt fragment it was found in is evidence item# PI/995. The shirt fragment itself was picked up by searchers amongst lots of other debris from the crash site.
How does it connect to the bombing of PA103?
Short answer, We don't know.
Longer answer, despite being found in a bomb damaged shirt fragment, which puts it definitively inside the bomb suitcase, we can't say for sure whether or not this PCB fragment comes from the bomb itself, or was just an item in the case. If you take the view that it did form part of the bomb, which is the most likely explanation if it's provenance is genuine, then it links an MST-13 timer to the bombing and by extension MeBo.
Who does it implicate?
MeBo and whoever they sold their timers to. MeBo claim during evidence at trial to have sold 20 such timers to Libya in 1985. Also at trial it was testified by a former Stasi member that MeBo also supplied timers to the Stasi (East German secret police) circa 1985.
Megrahi was the guy tasked with obtaining items currently blocked by sanctions for Libya, and he was a known associate of Edwin Bollier, the man who ran MeBo.
Above is basically the reasoning used by the "official story" to tie Megrahi to the bombing via Libya and their procurement of MST-13 timers. Which on first glance looks fairly solid. However, it all falls apart when you start looking much closer.
Lets start with Dr Thomas Hayes. He was head of the explosives forensics lab at RARDE, the govt lab tasked with investigating anything explosives related. To say Hayes has a checkered history is something of an understatement. He previously worked on other high profile cases like that of the Maguire 7. The Maguire 7 were essentially convicted on the back of Hayes "expert forensic evidence" and it proved very wrong. The cases were quashed and after spending 15 years in prison for something they didn't do they were released. The appeal court noting that RARDE scientists had "lied and deliberately suppressed evidence" There were several other such cases, but suffice it to say that Dr Hayes was a man promoted far above his skill level, he was slapdash, disorganised, poorly qualified, and despite all of that his word in court as an "expert" witness held a lot of sway.
He claims to have found Pt/35b May 12th 1989. Only his contemporaneous notes were kept in a loose leaf(!) file and the page he used to note PT/35bs discovery was inserted at a later date into this file and subsequent pages of that file were renumbered. A situation Hayes himself at trial called an "unfathomable mystery" His colleague Dr Feraday, who was later promoted to Hayes job after he quit in late 1989 and who shares many of Hayes shortcomings (Both Hayes and Feraday were prominent scientists at RARDE involved in preparing evidence for the Maguire 7 trial, which got such scathing comments from the appeals court) was also unable to explain Hayes notes and the page numbering anomaly at trial when he was asked to do so.
We know for sure that PT/35b was known about on May 22nd. Photo 117 of the RARDE report shows PT/35b and the photo register dates that picture to May 22nd.
So we know that Hayes was at best a terrible forensic scientist, and at worst a willing stooge who has previous form of fabricating evidence, lying in court and suppressing other evidence.
So the entire provenance of this fragment is called into question.
The evidence bag containing PI/995, the bomb damaged clothing fragments was not examined until May 12 1989. So it sat in a storeroom for ~4 months between being picked up near Lockerbie and finally being examined. Ample time for someone to have tampered with it. We don't know how good security was around wherever it was stored, we can't say whether there would have been opportunity to tamper with evidence, but there would have been time to do it, and there was certainly motive to do so.
How was Pt/35b identified?
Enter Tom Thurman. June 14th 1990 in an interim report signed by both Hayes and Feraday they note that despite a great deal of effort to identify fragments of bomb circuitry to date nothing had been identified. (There is a great timeline here that show in detail a lot of the work that was done up till then to try to identify PT/35b)
It took American intelligence agencies to identify PT/35b as a fragment of an MST-13. Tom Thurman of the FBI takes the credit for it, though it was actually CIA analyst John Orkin that made the identification. Thurman claims to have been given a complete timer circuit (K1) on June 15th. Though in fact the CIA had possession of K1 since 1987.
On June 22nd Scots investigators visited the FBI in Washington where Tom Thurman showed them photos of the K1 timer sample and it's here that PT/35b is finally identified.
On the face of it a lot of painstaking police work to identify a unique PCB fragment, with co-operation between US and Scots investigators ultimately bears fruit.
PCB Testing
Large amounts of testing was conducted on PT/35b. Bits of it were cut off and analysed for metals present. It was looked at very carefully under microscopes and some of the reports conflict. You can read a long summary of scientific testing conducted in 1992 here and 1999/2000 here.
In short it was tested extensively and on balance it appears to be what it is claimed to be. A fragment of an MST-13 timer, made by MeBo, that has been damaged consistent to being in close proximity to an explosion.
MeBo was a tiny company and it's PCBs were essentially handmade. As such they contain irregularities you wouldn't get from mass produced machine made PCBs.
Timing is everything
In my head it all really comes down to one main point. MST-13 timers are clock timers. You either set a time for it to go off, or start a countdown and when the designated time is reached, or the countdown elapses, the timer activates. Why would you not set a clock timer to activate mid-flight?
If the bomb detonated midflight the plane would come down over the Atlantic and most of the debris (and any incriminating evidence it contained) would likely be lost forever at the bottom of the ocean.
It was close to Christmas, flight schedules are notorious for being late to take off at the best of times.
We know that the bomb case was planted at Heathrow the night before the flight departed.
The main alternate bomb theory is that the bomb was made by Khreesat and used an altimeter timer. As soon as an altimeter timer detects the preset atmospheric pressure it activates. It won't guarantee a mid flight detonation but it will make sure the plane is at cruising altitude.
The timing around the discovery of and identification of the MST-13 timer is also suspect. Initial investigations led police towards the PFLP-GC and Khreesat and an Iranian revenge plot. This was politically inconvenient on a number of levels for the US and the UK as noted by Paul Foot. He describes in his "Flight From Justice" a WaPo article circa 1990 by Jack Anderson describing conversations between UK PM Margaret Thatcher and US President G HW Bush and a decision made between them to downplay Iranian involvement in March 1989. Why this decision was taken is anyones guess. But the timing is curious.
March 1989 is weeks before PT/35b is discovered in evidence bag PI/995.
American intelligence have a timer they know to be uniquely manufactured by a small electronics company, in their possession in 1987, that would exclusively tie a bomb to Libya (and away from Iran) once it had been identified.
In Summary
Why do I believe PT/35b was planted?
For the timer to be genuinely part of the device that brought down PA103 the following must all be true.
i) The bombers chose a really dumb time to activate their bomb
ii) The bombers used a unique timer. A clock timer is a very simple device and there are thousands of options, but they used this one particular timer that can only have come from one source.
iii) Despite Hayes previous form he conducted honest and truthful analysis on the Lockerbie evidence and his misnumbered notes was an honest mistake.
iv) The way that the timing of the fragments discovery lines up with politcal considerations is just a coincidence.
I can believe that one or two of these is true, all four of them though starts to strain credibility.
I believe that a political decision was taken at the highest levels of govt in March 1989 to steer investigations away from Iran and towards a n other bad actor. I think that PT/35b is indeed an explosion damaged fragment of a genuine MST-13 board, but I think it was planted in late March 1989 into evidence bag PI/995. Perhaps it's identity was discovered through honest police work by determined investigators, perhaps people in the US were nudged towards its identification.
I think that a bomber would set a clock timer to detonate mid-atlantic and not relatively shortly after take off.
I think that Hayes in particular having previous form for lying under oath and misrepresenting forensic evidence gave the powers that be a window that they used. (I don't think Hayes is a bad person, I think he believed he was doing the best he could to put bad people in prison, though I do think he is utterly incompetent)
I think that on balance the evidence shows manipulation, it shows convenient timing and the weight of evidence in all probability supports PT/35b not to be a genuine part of the timing circuitry used in the bomb that brought down PA103.
That's the crux of my hypothesis. I might be wrong. I'd welcome other evidence to show where I might be wrong.
