The poor airmanship was earlier on when he floated over halfway down the runway before touchdown when he should have gone around.
Exactly. No excuse using that much runway up floating trying to achieve a smooth landing. He got away with it this time, but the next...
Besides that, I'm pretty sure I know the guy who was flying it and he was famous, or should I say infamous for using way too damn much runway trying to get smooth landings.
As the 'passengers' on the aircraft were deportees and/or prisoners, who the hell cares what they think of the landing. To be sure, I always tried to make the smoothest landing I could regardless of who was in the back, but not to the extent this guy did in this video.
He should have planted it on the runway or gone around. No excuse for landing as far down the runway as he did.
