"22" Sorry for being a bit dull but what has the management of either airport got to do with diversions?
Seems to me the pilots elected to take the safe(r) option.
All "pressonitis" does is get people killed.
I believe if I wasn't happy to make the approach for whatever reason, the last things that would go through my mind is company profit or which management team is running which airport. Quite frankly all I'm looking for is a piece of clear concrete/tarmac (pehaps with a CAT 3 ILS), competent air traffic (which we seem to get in NI) and a well trained ARFS.
I think the bmi pilots who diverted probably thought that too and no one should criticise the PIC for having the balls to divert.
