which flight would you rather be on?
The cheapest one, I'll take my chances, as I do every day when I get into my car, a young driver may lose control of his/her vehicle and snuff me out in a moment, if your time is up, it's up, you have no say in the matter.
If the fuel tanks on QF32 ignited, it doesn't matter how many hours the tech crew have, the result would have been the same.
