"Doesn't the fact that nobody has done such an obvious, long overdue survey indicate that they know exactly what they will eventually find?"
Not to me it doesn't, I'm not convinced it's "obvious", any more so than the supposed link between flying and cancer is "obvious".
"Why are pilots discouraged from donating blood?"
Are they? First I've heard of it, nobody discouraged me from donating blood the last time I did it so where has your info come from?
"26 out of 26 pilots had highly abnormal blood results in 2006 - ask BALPA, they know ALL about it".
Without knowing the context that's a meaningless comment...I know dozens if not hundreds of pilots who fly or have flown the 757 or the 146 who haven't got abnormal anything. As for "BALPA knowing ALL about it" well, yes, they do have an opinion on the Aerotoxic campaign, but possibly not the same one as you.
