Hairyplane - an intelligent and considered addition. I only hope our Street of Shame tormentors will read it. How anyone armed with what I expect is a good degree can go into that profession and sleep at night I cannot imagine.
As someone whose recent life has consisted of 6 earlies, 2 days off then 6 earlies (which should of course be illegal but as a 7.30 take off on the continent doesnt count as an early despite a body clock 4.30 alarm call) I know how debilitating fatigue can be - far more dangerous than 2 or three pints 9 hours earlier. Now that is worth a serious investigation - but of course that would mean some hard work and the headline 'Pilots forget to arm Localiser due to Tiredness' doesnt really look as good in 44 point.
