When & How?

We have been told at least four different stories about how and when PT/35(b) was found and when it was examined. Let us review the various statements.

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 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).

A shredded shirt containing the fragment was found by a Scotsman walking his dog after the formal recovery effort had ended. […] This farmer saw this fabric, looked at it, knew, of course, the plane had crashed… and brought it to the attention of the Scottish police. The shirt had been destroyed . However, … the label in the back of the collar had a tag that linked it to Mary’s House…


On 22 January 1990, Scottisch scientists of the Royal Armement Research and Development Establishment (RARDE) found a fragment of a green circuit board lodged in the cuff of a “Slalom” shirt which was identified as “PT 35”, and could have possibly been part of the detonator…
