of the firm's MST-13 timers. Lumpert agreed that the fragments shown to him in court "could be" from that timer and was asked to confirm his signature on a letter concerning a technical fault with the prototype MST-13 timer. The trial was then adjourned until 12 July 2000. On 18 July 2007 Lumpert admitted he had lied at the trial. In an affidavit before a Zurich notary, Lumpert stated that he had stolen a prototype MST-13 timer PC-board from Mebo and gave it without permission on 22 June 1989, to "an official person investigating the Lockerbie case". Dr Hans Köchler, UN observer at the Lockerbie trial, who was sent a copy of Lumpert's affidavit, said: "The Scottish authorities are now obliged to investigate this situation. Not only has Mr Lumpert admitted to stealing a sample of the timer, but to the fact he gave it to an official and then lied in court". In week 11, Mebo lawyer Dieter Neupert filed an official criminal complaint against the Crown over what he alleged was a 'forged fragment of MST-13 timer'. Tony Gauci of Mary's House, Sliema in Malta, testified that he had sold a number of items of clothing to one of the defendants, Megrahi. Wilfred Borg, Ground Operations Manager at Malta's Luqa airport, was questioned about Luqa's baggage handling procedures. A Mr Ferrugia confirmed that he had been a passenger on Air Malta flight KM 180 to Frankfurt on 21 December 1988. Two Germans, Birgit Seliger and Evelin Steinwandt, confirmed in week 12 that they had also travelled on flight KM 180. Martin Huebner and Joachim Koscha were questioned about baggage handling procedures at Frankfurt airport. Five more passengers on flight KM 180 testified in week 13. The captain of flight KM 180, Khalil Lahoud, also gave evidence and was asked to confirm that the aircraft's altitude during the flight had exceeded 30,000 ft. This information was intended to demonstrate that an IED loaded at Luqa airport would have had a timed detonator rather than a barometric trigger. The trial was then adjourned until 22 August 2000. In week 17, another four passengers on flight KM 180 were asked to testify. The following week, Abdul Majid Giaka, a defector from the Libyan intelligence service, appeared wearing sunglasses and a wig. Giaka, who had been on the US Witness Protection Program since July 1991, testified that Megrahi was a Libyan agent.
