Yes I was the radio operator seconded from the RAF to the BBC for their Expedition Turtle to Aldabra Atoll c. 1966. The purpose of the BBC Expedition was to assess the possibility for siting radio radio rebroadcast facilities. It was very much dependent upon continued military interest, since that would entailed an airfield being built. There was some MoD input into the Expedition mainly in the form of surveyors. More interesting was that there were also two USAF colonels. At that time America was heavily into Vietnam and they wanted an Eastabout route as well as their existing Westabout one. In particular they wanted transit facilities for the F111, which needed to island hop to get to Vietnam. A deal would be made for landing rights in exchange for development dollars ! The BBC had hired the MV Southern Skies, out of Mombassa, for the Expedition. It was really a 600 ton coastal waters , general purpose vessel . The expedition was to have lasted 6 weeks, but towards the end tropical depression 'Angela' started to head our way . A 600 ton vessel is not the best of craft to ride out a hurricane, so the Expedition was curtailed and we hightailed it for Mombassa
