This video clip shows a Turkish Airlines Boeing 737-900 coming in to land. It's too fast and too low, so it makes a bumpy arrival, bouncing clear into the air again. The spoilers deploy automatically on impact, dumping the wings' lift: but the plane's still moving too fast. As it touches down again, the pilot clearly decides that he's pushed his luck far enough for one day, and elects to take off again and go around for another try. Note the tail strike as he over-rotates the aircraft.
Methinks that pilot could do with some serious re-training . . .
