If I, as a Bonanza driver, was sitting merrily in Economy Class on QF1 and the FA came up to me in the middle of the night and asked me to come up to the pointy end and give the sole pilot a rest break .... I think I would have the intelligence to say no.
If I was a QF 737 jockey, repositioning back to base on QF1, and was asked the same question .... what would I say?
If I was a QF 737 jockey, on duty, with the task of providing the 747 Captain with a rest break ... what would I do?
