Locked door / Cessnapete
I am very sorry but the anecdotal evidence was two trainers who's conversation at Cranebank was a bit louder than I'd should have been and was within earshot of an independent third party.
Having started an aviation carreer inside BA I found that 95% of the people just wanted to progress in a trouble free way along a normal carreer path but there was a small number of very nasty climbers of the slippery pole who would do just about anything to gain an advantage! I would hazard a guess that it is the 5% who see the BMI people as an easy target.
