The passengers always applaud.
No landing configuration, thy try to scary pax? When they had a technical problem, they must choose a longe runway!
Passenger's video here.
Landing configuration too late, came in "hot and high"...and most noticeably, didn't commit to the error and to the go-around.
As the old saying goes...can't use the part of the runway that's behind you. Anyway, there might have been a technical problem...even at touchsown, to me the flaps don't look like they're in landing config really, are they?
Thinking about the "technical problem" bit though, I think he would have diverted to an even longer runway. Or at least they would have deployed the fire brigade...none to be seen along the runway...
