P47 Don't ever ever stall. That works equally well in any airliner including an A320. Sully knew that so wouldn't have stalled prior to splashdown. If the Airbus computer didn't give him the last 3 degrees of AOA in the flare before stall it still worked so everybody got out alive. The next A320 crew might add 20 knots to the approach speed to counteract the computer to get a zero descent touchdown. You still touch down at the minimum speed since you have a long river and can flare as long as you want. I loved his video. He was totally in control. He knew he had to have the wings perfectly level on touchdown. I loved his book.
