[It was on this date in 2007 that Ulrich Lumpert, a former employee of Mebo Ltd in Zürich who had given evidence at the Zeist trial about MST-13 timers, swore an affidavit to the effect that his evidence had been false. An English translation of the affidavit can be read here. What follows is a comment that I made at the time:]
Ulrich Lumpert, an engineer at one time employed by MEBO in Zürich, gave evidence at the Lockerbie trial that a fragment of circuit board allegedly found amongst the aircraft debris (and which was absolutely crucial to the prosecution contention that the bomb which destroyed Pan Am 103 was linked to Libya) was part of an operative MST-13 timer manufactured by MEBO. In an affidavit sworn in Switzerland in July 2007 (available on the website www.lockerbie.ch) Lumpert now states that the fragment produced in court was in fact part of a non-operational demonstration circuit board that he himself had removed from the premises of MEBO and had handed over to a Lockerbie investigator on 22 June 1989 (six months AFTER the destruction of Pan Am 103).
If this is true, then it totally demolishes the prosecution version of how the aircraft was destroyed, as well, of course, as demonstrating deliberate fabrication of evidence laid before the court.
