Without knowing the exact times and altitudes along with the vertical speeds it's hard to say. But seeing that in one minute the range was 1380fpm down, I would say that it looked like a Stuka approach to the casual observer! I sure hate to see all of the other guesstimates as to the cause. I am open to many but, initially, it looks like pilot error.

“The FAA said the ill-fated plane may have collided with something after it landed on the runway’s threshold, with local media showing video clips on YouTube and television footage of the plane’s emergency evacuation slides being deployed and people fleeing the wreckage. Skies seemed to have been clear at the time of the accident.”
