A section of the American airliner which exploded over Lockerbie 35 years ago is being transported to the US for the trial of the man accused of making the bomb.
The wreckage from the fuselage of Pan Am Flight 103 will form part of the evidence in the case against Abu Agila Masud.
The Libyan has been accused of making the bomb which destroyed the plane on 21 December 1988.
Relatives of the 270 victims have been informed of the transfer of the fuselage section, which is part of a formal evidence sharing process between Scottish and American prosecutors.
