LOCKERBIE 30th Anniversary — PT/35(b) : An Overview of the Lockerbie Case

“Without PT/35(b), there would have been no indictment.”

Richard Marquise — FBI Agent who led the US side of the Lockerbie investigation

“The Lockerbie trial is the most disgraceful miscarriage of justice in Scotland for 100 years. Every lawyer who has read the judgment says ‘this is nonsense’. It is nonsense.”

Robert Black QC FRSE – Professor Emeritus of Scots Law in the University of Edinburgh and best known as the “Architect of the Lockerbie Trial”

“I regard the Lockerbie verdict against Megrahi as a ‘Grand Monument to Human Stupidity’.  Indeed, the written opinion of the Lockerbie judges is a remarkable document that claims an ‘honoured place in the history of British miscarriages of justice.’ If the SCCRC Commission accepts the application for a full review, the infamous Zeist verdict doesn’t have a snowball’s chance in hell of surviving.”

INTEL TODAY — July 5 2017

PT/35(b) is a small fragment of a timer circuit that was allegedly found among the debris of Pan Am 103 near the town of Lockerbie.

After many years of studies, 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 and to steer the investigation away from the original suspects.

Perhaps you are not familiar with the Lockerbie case or your memory may be a bit fuzzy about this extraordinary affair that began three decades ago. Therefore, before discussing the properties of PT/35(b) and what it implies for the case, I have written a summary of the Lockerbie investigation and trial which you might find useful.

To mark the 30th Anniversary of the Pan Am 103 tragedy, INTEL TODAY will re-post one of our best Lockerbie stories every Wednesday until the end of the year. We would like to know what you think. Please, take this poll and encourage your friends to participate.

On this day (November 14 1991), the Lord Advocate (Lord Fraser of Carmyllie) and the acting United States Attorney General (William P Barr) jointly announced that they had obtained warrants for the arrest of Abdelbasset Ali Mohmed Al Megrahi and Al Amin Khalifa Fhimah. I believe that the indictment was broadcast live both in the US and the UK. If you have a video recording of this event, please contact me. I would like very much to have a copy of Robert Mueller’s presentation during the indictment. I want to hear what he said about PT/35(b). Thank you. Follow us on Twitter: @INTEL_TODAY

The Lockerbie Case — Official Timeline & Legal Truth

On 21 December 1988 Pan Am flight 103 fell out of the sky. All 259 passengers and crew members died. Eleven residents of Lockerbie were killed.

A strong westerly wind spread the debris over two trails stretching from the south of Scotland through the north of England and out into the North Sea.

On 28 December 1988, Michael Charles, Inspector of Accidents for the AAIB, announced that traces of high explosive had been found on two pieces of metal. On that date, a criminal investigation was officially launched. The crime scene covered about 845 square miles.

On 13 January 1989, Detective Constables Thomas Gilchrist and Thomas McColm found a fragment of charred clothing in search sector I, near Newcastleton. This piece of charred grey cloth was bagged, labelled “Charred Debris” and given a reference number: PI/995.

On 17 January 1989, it was registered in the Dexstar log.

On 6 February 1989, PI/995 was sent to the Forensic Explosives Laboratory at Fort Halstead in Kent for forensic examination.

On 12 May 1989, Dr. Thomas Hayes examined PI/995. Inside the cloth, Dr.Hayes found fragments of paper, fragments of black plastic and a tiny piece of circuitry. Dr. Hayes gave to these items the reference number PT/35 as well as an alphabetical suffix to each one of them. The fragment of the circuit board was named PT/35 (b).

In June 1990, with some help from the FBI, Allen Feraday of the Explosives Laboratory was able to match PT/35 (b) to the board of  a Swiss timer known as a MST-13 timer.

Two MST-13 timers had been seized in Togo in September 1986. BATF agent Richard Sherrow had brought one of these back to the US. Two Libyan citizens were caught in possession of an other MST-13 timer in Senegal in 1988.

An analysis of the Togo timer led the investigators to a small business named MEBO in Zürich. The owners of MEBO told the investigators that these timers had been manufactured to the order of two Libyans: Ezzadin Hinshin, the director of the Central Security Organisation of the Libyan External Security Organisation and Said Rashid, the head of the Operations Administration of the ESO.

On 14 November 1991, the Lord Advocate and the acting United States Attorney General jointly announced that they had obtained warrants for the arrest of Abdelbasset Ali Mohmed Al Megrahi and Al Amin Khalifa Fhimah.

On 27 November 1991, the British and United States Governments issued a joint statement calling on the Libyan government to surrender the two men for trial.

On 21 January 1992, the United Nations Security Council adopted resolution 731 calling on Libya to surrender Megrahi and Fhimah for trial either in the United States or in the United Kingdom.

On 31 March 1992, the Security Council passed resolution 748 imposing mandatory sanctions on Libya for failing to hand over Megrahi and Fhimah. On 11 November 1993, the Security Council passed resolution 883 that imposed further international sanctions on Libya.

On 31 January 2001, a Court found Megrahi guilty and Fimah not guilty.

On 28 June 2007, the SCCRC announced that Megrahi may have been the victim of a miscarriage of justice. The SCCRC announced that there were six grounds upon which it had concluded that a miscarriage of justice might have occurred. Accordingly, the SCCRC decided to refer the case to the Court of Criminal Appeal.

On 25 July 2009, Megrahi  applied to be released from jail on compassionate grounds. On 12 August 2009, Megrahi — under enormous pressure — applied to have his second appeal dropped. Megrahi was granted compassionate release for his terminal prostate cancer.

On 20 August 2009, Megrahi was released from prison and returned to Libya where he died on May 20 2012.

On July 4 2017, the Scottish Criminal Cases Review Commission [SCCRC] confirmed that it has received a new application to review the conviction in the case of Abdelbaset Ali Mohmed Al-Megrahi.

Professor Black — who is known as the architect of the Lockerbie trial — has explained for INTEL TODAY the role and competence of the SCCRC.

On May 3 2018, SCCRC chief executive Gerard Sinclair  stated that “the (SCCRC) commission has decided that it is in the interests of justice to accept the current application for a full review of his conviction.”

Let us hope that the SCCRC will give TRUTH a chance!

About Lockerbie and Pan Am 103

For those interested in the Lockerbie Trial tragedy, I recommend the excellent blog of Professor Robert Black: TheLockerbieCase.

Those who want to study the forensic history of PT/35(b) will find many resources and original documents on the  PT35B blog. Also, you may want to check the blog of Dr Jim Swire and Peter Biddulph: The LockerbieTruth.

The book “Megrahi: You Are My Jury: The Lockerbie Evidence” by John Ashton is truly excellent and a must-read.

President Ronald Reagan comments on PAN AM 103 plane crash that carried some Americans  

Reagan is obviously at pain to explain why NOTHING was done about the Helsinki warning. The US President is also asked why the civilians — unlike the US diplomats in Moscow — were NOT told about the Helsinki warning.


A warning of a terrorist attack was broadly circulated to Americans in Moscow a week before the December 1988 explosion of Pan Am Flight 103 over Lockerbie, Scotland.

“It named a carrier {Pan Am}. It named a route {Frankfurt to the United States}. And it covered a time period” when many Americans in Moscow would be going home for Christmas, Smith said. “Here, it seems to me we have a moral obligation to let people know.”

The warning was posted Dec. 14 at a number of places, including the embassy’s press office, the commercial office frequented by American businessmen, the U.S. Information Service where students congregate, the Anglo-American school, and a bulletin board at the entrance to the cafeteria in the new U.S. Embassy complex.

Jennifer S. Young, who was Pan Am station manager in Moscow, said a reservations clerk told her of the posting. Young, in turn, sent a telex to Pan Am officials in Frankfurt asserting that “approximately 80 percent” of Pan Am’s holiday traffic from the embassy was “now rebooking” to other flights.

Also, notice that a journalist already suggested that Iran had a role in the tragedy at a time where no evidence of a bombing had been found and mechanical failure was suspected.
