How 'Naive' we were then.....
When 'committing aviation' ex Hedland, I can remember seeing Mr Tait in a Shrike at Hedland in the early 70's, it had 'Loran Geophysical Survey' or somesuch painted on the sides, and his story was that he was doing a 'Loran' / Geo survey....
No-one really knew what that was.
I guess it was sufficient 'cover' at the time though....Nice fella to talk to....
It was said at the time of his arrest, - Groggy's post - that after the successful delivery of that 'cargo' he would have actually owned the aircraft.
