The aircraft might have been on a stable, 500-per-minute descent, but I didn’t see the flare near the end to arrest the descent. I’m not surprised to see this result in collapse of the landing gear and snapping at the right wing off.
It is difficult to land on a snow-covered runway.
Yeah, I didn’t see a flare either.
Lots we don’t know, like what was the crosswind component, what’s the correct airspeed and flap settings for that approach. On and on.
