I've wondered if the Sioux City airplane had managed to land, at over 200 knots and with no hydraulics (thus no brakes, no reverse, no speed brakes etc) how would the pilots have managed to stop it? One would hope that they could have landed on the grass, thus using the drag of the gear as it buried itself in the ground, but on a long, hard surface they would have seen the end of the runway, and the buildings located there, coming up pretty fast!
But they did save over half of the passengers, gotta give 'em credit.
