The last guy to do maintenance and the pilot who did the walk round both failed to do their jobs properly.
It's as simple as that.
Maybe, but in the interests of it not happening to me or anyone else here I'd like to know in depth what happened that morning before the walkround.
In the crew's case I'd be asking if there was any hassle over the crew bus to T5 running on time? When they got to T5 did they struggle to find a serviceable PC, printer and/or stapler (that's a long story that I suspect will prompt a few
from the likes of NOD.) Was it possible the queue for crew screening was backed up well into crew report (
again). All this
might have been against a background of subtle but publicy displayed management demands that the first wave should depart on time.
Not excusing the fact that the latches may have been missed, and that the walkround was the last line of defence, but I'd rather not string my colleagues up quite yet..
