Perhaps those not voting are close to retirement and took the decision that the choice wasn't theirs to make?
I know for sure there was a bit of that (and I understand the logic) but I don't we've got a rough total of 800'ish pilots so close to retirement that they all aren't going to cast a vote (though of course I agree it depends how you define close)...

i thought the turnout was 65%
From my e-mail from BALPA: "Ballot Return 79.8%"..
FWIW there was a bit of confusion caused by one or two "wags" on the Union forum chucking some ficticious figures around just before the official announcement....
