Let us consider the situation....
You are on a one of the most complex vehicles constructed by man each part made by the lowest bidder. Furthermore, many of the parts have been scavenged from other such vehicles, installed and re-installed many times. Now then this vehicle is fueled by the two of the most bang worthy elements known to man - which you mix and light....oh and you keep the fuel in a big tank next to two of the bigggest fireworks ever made....
If anything serious goes wrong in the early part of the flight...you probably die
If anything serious goes wrong in the cruise....you probably die
If anything serious goes wrong in the descent...you probably die
and there ain't no go around...
Yep...I might want a stiffener before flying the fecker too
