To give you an idea of the depth and difficulty of questions you could be faced with, here is one that was asked of someone I know who went to OASC recently.
"What is special about the Merlin helicopter?"
The answer the "staff" were looking for is that it has 3 engines!!
The question was put to a chap applying for an aircrew trade, but was asked by some scribbly/supplier staff member who knew nothing at all about the Merlin himself, he was just looking for the candidate to provide the answer written on his magic script!!
Nuff said!!!!
P.S Ah BEagle, I spent much of my youth reading 'Battler Brittan' stories, purchased with my hard won and limited pocket money, you almost brought a tear to an old mans eye. What do the youff of today read I wonder?
