Maybe if the public knew how often pilots fall asleep whilst they're on their way to Spain (and everywhere else) they might think again.
I've flown dozens of sectors (as have many of us) when the other pilot was asleep for part of the trip - sometimes without knowing it - and on one occasion denying it as he had no idea he'd drifted off!
I've never fallen asleep myself, but I've been EXTREMELY fatigued - and on one occasion developed a 'poorly tummy' to enable me to get off the duty in between sectors because I couldn't function property I was so tired.
I'm sure the public have visions of two, fit, alert individuals flying the aeroplane when, in fact, they are almost certainly fatigued to some degree and possibly asleep.
Happy days! not
