True, however he's the one who posted it on the nosy pilots forum. Advice on whether or not he should quit or allow himself to be fired thus rests entirely upon whether or not this was a stupid pilot trick or an unavoidable incident. Either way, it's hard to say without having any context of the accident.
Hiring an aviation attorney is probably money down the drain, at $250 plus per hour what's he fighting for... there is no recourse for this on a wrongful termination suit in any at will state in this country. Even if he won he'd likely only cover enough to pay the lawyer, maybe. Best advice is if it was a stupid pilot trick and he should have spoken up, resign.. otherwise be fired.
That is an impressively built card house of logic there. I should go wake up the Beagle-mix so he can have a peek too. BRB
