  Nothing worse than a plane crash
context: I doubt there will be any survivors considering footage. It banks heavily on the left which takes away any chance at a somewhat controlled crash landing.

  Stalls like this can happen with the engines working normally. The nose looks way higher than a normal approach to me, and they’re obviously slow. Too slow/too high AoA and the wings lose lift, but that doesn’t always happen symmetrically with the nose dropping. Instead one wing can lose lift first, causing a banking dive like what’s in the video.
  Assuming the engines were running normally, this could have been avoided by adding power and lowering the nose even just a couple of degrees. Inexperienced/poorly trained/panicking pilots might increase power and raise the nose instead, which then leads to a stall.
