Blimey! What absolutely amazingly important news!
I'm sorry to get my flame thrower out at this early hour buddy but this one is so old it creaks. Anyone doing a bit of research on this site or almost anywhere else will hear this story at some point. It might be true, it might not be - either way, unless you are in charge of policy at the aforementioned school, it will be difficult to prove or disprove the accusation. Sure, there is quite a lot of anecdotal evidence supporting your case but that isn't proof.
Anyone sensible is going to do a bit of hunting when looking to spend the kind of money we're spending on aeroplanes. There's enough info around to help make peoples' mind up whatever way. Can't we move the debate forward instead of recycling the same old chestnuts - it's getting boring!
PS Usual caveat - I didn't train at OAT and am not connected with them in any way even slightly.
