After watching it several times clearly the nose was too high, and coming in to fast at a sharp angle. Those rotary craft can bite you if you aren't right on them that last 50 feet. I can't believe nobody was killed. it looked like one guy fell out.
I spent 4 years with Vietnam combat veteran helicopter pilots and crew chiefs, and those guys made landing a Huey look like a walk in the park.
Those crew members were literally standing on the skid tubes like waiting for an elevator, and when the chopper got within 3-4 feet of the ground, they just jumped out and went out at a dead run!(Infantry and PJ's) and the pilots gently touched the ground, no bounce.
Great guys they were too,,,,,,,,,
