The reasoning is nevertheless flawed. His answers are reproduced under each picture. His instructions from them were that any bomb he made must not be primed. Similarly, we cannot exclude the possibility that other MST timers may have been he by MEBO and supplied to other parties, but there is no positive evidence that they were.

Sorry, your blog cannot share posts by email. It is therefore unlikely that the Commission would have been any less constrained in its ability to disclose the documents had it made use of its statutory powers. This is a rather simple fact. Here is a good quality pic of 44518 board 4158 There was no evidence that the cell had the materials necessary to manufacture an explosive device of the type that destroyed PA This the design of the main MST board.

Contrary to what Marquise seems to believe [3], this number was not deduced from the number of Thuring boards MEBO had ordered. The potential order was for a large number of such timers. I must now tell you about another feature of the MST Timers: Equally, despite the evidence of Mr Wenzel that after the fall of the Berlin wall he had destroyed all timers supplied to the Stasi, we are unable to exclude the possibility that any MST timers in the hands of the Stasi left their possession, although there is no positive evidence that they did and in particular that they were supplied to the PFLP-GC.

The FBI report on the Togo timer does not mention the watermark on the main board of the timer. MST Delivery to Hrf. He was sentenced to imprisonment for fifteen years.

The MST-13 Timers

There is a dispute in the evidence between Mr Bollier and Mr Gef on the one hand and Mr Lumpert on the other about the colour of the circuit boards in these prototype timers. The evidence which we accept showed that at least at that time the cell had both the means and the intention to manufacture bombs which could be used to destroy civil aircraft. The main board is exactly the same in both cases.


A total of twenty were built by Lumpert, ten for use in a waterproof container boxed and ten which were free standing unboxed. How many different types were designed and how many were built? According to a further delivery note CPimage 1Thuring supplied 34 such circuit boards on 5 November Notice the not hed professional handiwork. It is possible, of course, that the cell could have re-grouped her re-stocked with the necessary materials by 21 December.

A similar account was given by him when questioned by the Scottish police in Libya on 30 October see appendix. Photo 8 an oscillator crystal. Schweizerische Isolawerke AG in Breitenbach.

I think that it must have been written between 26 September and 11 December Moreover, while he himself did not give evidence, there was evidence of a statement given by him to FBI agents production in which he said that he never used radio cassette players with twin speakers such as the Toshiba RT-SF 16 had to convert into explosive devices.

In the case of these Thuring boards, it is actually a mix of Lead and Tin. In particular they raided premises at Sandweg 28, Frankfurt and the home of Hashem Abassi in Neuss and they seized a car which had been used by Haj Hafez Kassem Dalkamoni, apparently the leader of the cell.

The last ten were delivered Hijazi [2], a high ranking Intelligence officer, in Tripoli. From other evidence it appeared that one of theairline timetables was a PanAm timetable.

Bollier often visits me in the laboratory and helps with simple technical work and I remember that in about the summer of he soldered a battery and cable onto an MST timer. What we do however accept is that later in the summer of the two prototypes were delivered by Mr Bollier to 45188 Stasi in East Berlin, whatever be the colour of their circuit boards.


In any event, even if an order had been obtained by the Commission under section of the Act, in terms of paragraph 6 5 of Schedule 9A it would have been open to Crown Office to hev the Commission that onward disclosure might be contrary to the interests of national security. It must be one of the pre-series timers. This is not surprising as the report signed by Thurman is almost a copy of the CIA report.

This point was clearly noticed in the CIA Report.

In these premises hff found radio cassette players, explosives, detonators, timers, barometric pressure devices, arms, ammunition and other items, including a number of airline timetables and seven unused Lufthansa luggage tags. This is a pre-series timer because the condenser has been soldered diagonally and the soldering points near the switches of the power cable have not been covered with a plastic protective sheet On the other hand I can verity that the circuit board has been coated with a protective lacquer which points to a later development of circuit board.

The models being used were, however, different hev the RT SF used in the PA disaster, and the timers were of a type known as ice-cube timers.

The pre-series timers had protective lacquer only on one side. Photo 6 This is one of our secondary circuit boards. On the evidence which we heard we are satisfied that the explosive device which destroyed PA was triggered by an MST timer hev and that neither an ice-cube timer nor any barometric device played any part in it.

Photo 1 is one of our timers although I do not recognize hed black electric cable. Solving a 30 years Old Mystery. Photo 7 This is an oscillator with hwf resistors which were added later. Yet, its consequences are not without merit. The first five were delivered by Bollier to Fazani in Libya in the late fall of On the other hand I can verity that the circuit board has been coated with a protective lacquer which points to a later development of circuit board.

I have found the explanation to this discrepancy.
