There are many videos online that claim to show the crash, most of them fake.
But this video, supposedly made by affiliates of ISIS to claim responsibility for the explosion, seems to be real.
Security experts think that the 90 second clip, which shows the crash from two different perspectives, could indeed have been taken by the terrorists.
Both the size of the plane shown in the video and the explosion fit in well with what we already know about the crash.
Most tellingly, the fact that the video was shot from two different perspectives means that the people who made the video already knew what was about to happen.
Both British and American investigators now think that the attack was almost certainly carried out by ISIS or its supporters.
