In 36 years of flying ( gulp ) I can only remember a couple of occasions when things went a little astray.
Firstly, when flying as an FO on a 1/11 and teamed up with a very under-confident albeit technically experienced Captain ( funny how I always flew the thing in bad weather ). A little too quick for him one morning whilst still on the ground - his teddy went out of the window and a subdued day followed !
Secondly, years later, when flying with another Captain ( run out of co-pilots again ) - swapped seats after first leg and it all went a bit astray. Sorted out with a handshake in the cruise - he was a mate before the 'incident' and has remained so ever since.
Forget about all this civ/mil debate - there are clowns from both backgrounds but fortunately these events as reported in the tabloids are few and far between - at least I hope they are !
