There was a cracking article in a flypast magazine about them quite a while back, one they believe was taken out by a German spy, there was an incident in a hotel and during it they believe the pilots flask was swopped with one containing a bomb that detonated on the way to the UK killing the crew, another incident referred to the carriage of VIP passengers who were simply perched in a hammock strung along the bomb bay, the doors being then shut... one passenger had the misfortune of the bomb doors drop open enroute, so was left lying there on his hammock looking at nothing below him but the sea!
