What makes you say they didn't land on the rear landing gear first? Part of the normal landing is -- AIUI, IANAPilot -- to flare, that is to increase the angle of attack of the aircraft (pull up the nose, increase drag) in order to reduce forward speed; this also puts the rear gear closest to the runway, the rear gear being bilateral means this spreads the load. In fact, I've just looked at a video on YouTube "AIRLIVE" [0] and you can see the shadow of the nose off the ground when the plane shakes (at 0:07s) indicating the rear gear has made contact. I think the nose contacts at 0:13, so gently it's amazing. [0] https://youtube.com/watch/I1dthJSuZLk https://youtube.com/watch/I1dthJSuZLk
