It's an interesting question. Perhaps an answer is, "he didn't f**k it up worse than it was".
I'm thinking about the 737 that crashed taking off out of National. There were all sorts of problems that put them in a bad situation including some frozen over engine sensors, inadequate deicing, slushy runway. They took off in a world of hurt, but all they didn't do is push the power levers forward when they realized they were descending. We may never have heard of the incident if they had but they f**ked up worse than it was. Colgan, Air France, etc. Things were bad but the crew f**ked up worse than it was.
Sully's team got about as bad a draw as you can get; multiple bird hits taking out both engines over one of the most densely populated areas on the planet. We just got done talking about the 'impossible turn'. If you had 100+ souls on board getting back to an airport would be a strong temptation, I mean, there's no way we lost all power on 2 engines simultaneously, there must be something left to get us back to LGA or over to TEB. ATC has just cleared us to return (not that it means a damn thing but given the short straw, following their lead is a distraction if not a temptation).
No, they just kept their heads on (unlike the Colgan rookies or the AirFrance pros) looked rationally at the situation and executed a ditch into an ice cold river. Piece of cake.
You are right... nothing spectacular about it. Just plane good pilot sh*t. When faced with that much f**k up, may we all be as good. I know you would be just as I would, yes.
