Is this man trapped in a horrible accident and does he eventually fall to his death inside this collapsing building? You be the judge by watching the video:
Initially it appears that this man is caught in a horrible accident as this building partially collapses with him still inside. However, if you carefully examine the footage, you can see that as the wall starts to fall, he jumps to the floor.
After the wall falls, he is lying on the floor where the window used to be. You cannot see him on the floor because of the angle of the camera. This is a very good fake, but it is a fake nonetheless.
The man gave himself away by his not so very good (meaning poor) acting. He feigns panic supposedly not knowing what to do as the wall begins to go. But it is not like any panic I have ever seen.
In addition the man is on the young side, and who is it who are always trying to put fake videos on YouTube? Young people. Nice fake though.
