The other point about acts of heroism is that it can come to define a person in a manner they themselves didn't want. I hope when those two pilots retire, they look back on this as the scariest day of their life, and not the defining moment. I certainly hope that Pilot Sully isn't drawn into some insane "Joe the Plumber"-style media showboat, though given that Joe wasn't actually a plumber, I can see how that all worked out.
Maybe I'l ruminate on this a bit more later.
