“Without PT/35(b), there would have been no indictment.”
Richard Marquise — FBI agent who lead the Lockerbie investigation
“PT/35(b) was extremely, extremely dodgy. It was very, very suspicious. The way it suddenly appeared, embedded in a shirt collar, with the information on the page overwritten and changed, all police procedures were thrown out of the window.”
Reverend John Mosey
“Dr. Hayes seemed to have no real recollection independently of his notes of having found PT/35(b). The sequence of the PT numbering and the absence from the notes of a drawing of the circuit board are unusual features. The pagination of the notes was described by Hayes as ‘an unfathomable mystery’, for which he did propose an explanation, but unfortunately one that does not work. The memorandum of the 15th of September 1989 is difficult to understand if the fragment was indeed found on the 12th of May 1989. PT/35(b) is an important piece of evidence on which the Crown rely and in respect of which it is for the Crown to satisfy the court as to its provenance. I submit that the irregularities and peculiarities which attend this item are some which the court ought to have some hesitation in being satisfied as to the item’s provenance.”
Defence counsel Richard Keen QC — Lockerbie trial (p. 9624)
“Please tell me what you do not believe about PT/35(b). (…) if anyone ever could show me one shred of evidence that anyone other than Megrahi and Libya did it, I would be willing to rethink my ideas. I have yet to see the one item of evidence.”

July 6 2020 — PT/35(b) is a riddle wrapped in a mystery inside an enigma. PT/35(b) is a small fragment of a timer circuit that, according to the Lockerbie verdict, triggered an IED onboard Pan Am 103. PT/35(b) was allegedly found among the debris of Pan Am 103 near the town of Lockerbie. After many years of study and research, I have come to the conclusion that PT/35(b) is a forgery that was planted among the debris to implicate Libya in the bombing of Pan Am 103.
