Golden Horn
I believe my uncle was one of the crew on Golden Horn. He told me he was not needed for the Air test (being what I understand today to be a loadmaster/cabin crew) so opted to stay on the ground trying the local wine. The captain invited some of the local VIP's/ dignitaries for a 'joyride' and set off for the air test. This was obviously lucky for my Uncle but very embarassing politically, when Portugal was supposed to be neutral. He gave me a photograph of a Sunderland burning in the water but I don't know if this was the same incident.
