I joined Bristow in spring 1968 and AB was the chairman of BUA then, seem to remember he wanted all the BUA pilots on contracts and was offering GBP5000.00 a year!!! Didn't happen.
The 'dress' for overseas postings was khaki shirt, trousers, 'suitable' footware, (pilots), the various interpretations of those dress instructions had to be seen to be believed! I was issued a cap but no other part of a uniform and the cap had the BUA badge on it, the cap was never worn and I think the hangar dog got it in AUH!
