I saw this film as a cadet back in the late 70s/early 80s and like one of the early posters on this thread I went out and bought the LP by Vangelis - still got it - sadly never got much closer to the Bucc than summer camps at St Athan when they were bringing the ex-RN airframes up to RAF standard, and then about ten years later probably visiting the same ones based at Lossiemouth.
In those days the careers office staff used to bring these along on 8mm cine film, I remember another one which I think was called Watchdogs and was all about RAF Germany as was. Happy - if a bit scary - days.
