When these two pilots touched down, both captains, they expected the airplane to stop but it didn't. They must have soon known they would not be able to stop. Would leaving the right engine TL above the idle detent cause all of this to happen? If so then AB needs to change their software. I have landed Boeings with one TR malfunctioning on short runways, TGU, and could see bumping up a TL if it had AB logic. I guess I just like to select something and get it rather than see if it is offered.
