Several Nimrod mates entered by this method. The RAF, Balpa & the CAA actively encouraged the process. Ratings were awarded by CAA examiners during flights & simulators with the hours provided freely by the RAF.
The advantage to the airlines was that the RAF had done all of the initial selection, training etc. It was a low cost, virtually risk free method of recruitment & it rewarded experienced military pilots who had willingly served their country.
For people to talk of discrimination & legal action only serves to prove how this country has changed, for the worse.
