All rather touch in cheek to get the message across I suppose and taking the micky out of the RAFP at the same time.
The point being made was the Flight Safety is everbody's business (apart, that is, from 'Mrs Doubtfire' at MPA who allegedly wrote on some Flight Safety missive 'Not for admin wing'....
). The Snowdrop had spotted what he thought was an insecure panel, so stopped what he was doing to rush off and report it before the aircraft took off. It was, in fact, the 125's APU intake door and quite normal; he didn't know that but was praised for having raised his concern.
It was a good Flight Safety film - can't remember much else about it, but I can certainly remember that 'laughing policeman' and the undercranked 'Benny Hill chase effect' of him chasing the aircraft on his bike!
