In this picture, we can see two different views. In the first one, on the left, we can see what used to be an engine from a passenger’s point of view. The engine fairing is severely damaged, the latches supposed to hold it to the aircraft are all opened, and the slats have impacts approximately at 1/3 of the wing. In the second part of the picture, on the right, we can see a blown-up window. With all these elements in mind, one could say that debris was blown away from the engine when it exploded and that the broke a window, leading to an explosive depressurization. The pilots successfully managed to get the aircraft on the ground.
