Would it be a sensible assumption that the pilot and the passenger were in a rush?
Possibly.
Yet another opportunity for accident avoidance? If I find myself getting into a rush around aeroplanes I quite deliberately stop, calm down, think, and go back a few steps in case I've missed something.
I've never yet got to the point of deciding "I'm not in the right mood for this, I'm going home" but I've heard of other people doing it and I'm aware it's an option.
A tommy restart is simply mixture rich, throttle crack, master switch on, turn the key, not the 50 or so checks listed.
Yes well, I got caught once doing the equivalent of that in a 172. The bit I missed out on the restart was making sure the fuel tap was pointing the right way.
