It bounced/skipped, then came down hard the second time
I opine (with no more information than the video itself) that prior to the "first" ground contact seen in the video, the aircraft had already touched down once, so "one" then "two" may really have been "two" then "three". Each ground contact was more violent than the preceding one. This has been seen before as an approach flown too fast, the pilot trying to force the plane onto the runway at too fast a speed (perhaps in this case, out of a sense of urgency for being on the ground, rather than in flight with another emergency), and a porpoised landing to destruction as the result. It does not appear that the nose was being held up to slow the plane into a flare.
