how does one do that?
The press reports describe the pilot as braking hard followed by abrupt acceleration--in order to throw the hijacker holding a gun to his head to the floor.
The abrupt acceleration seems puzzling, given real spool-up times, and 10200 feet of runway.
What does one do? Land Navy style--advancing the throttles on or just before touchdown, so that by the end of the braking pulse there will be enough thrust to give a useful jerk? Then heavy braking again?
Desperate situations require bold solutions--this fellow seems to have seen that as few do.
