Amazing that data is available like that, I didn´t know it was possible. It´s early to know because a number of things may have caused this profile, but initially it seems a quite unstabilized approach. For a plane as heavy as a 777 it´s difficult to loose altitude and speed as fast as a (for example) a MD80. For those who don´t know, the first aproach is a 3 degree normal glide path. The second one is almost double than that. That means maybe more than 1500´ /min of discend. If you are not used flying in such conditions (almost idle engines, steep discend, speed above aproach selection) it´s hard to slow down your descend without smashing your tail with the ground (is what it seems it happened) or overflying the runway due to the excess air speed. We´ll have to wait for the investigation and all the flight data to know what happened.
