Pause the video at 20 seconds...and look at the back of his legs...you see nothing but his cream colored pants. Freeze again at 25 seconds...and see the same thing.
Freeze at 37 seconds, and you see that he’s suddenly got a colorful ‘tail; drapped over his legs. Where did that come from?
Between 40 sec and 44 sec, his legs go way back, almost how a parachutist arches his back when in free-fall. Try to do this on a chair...while flapping your arms.
Around the 1:05 mark, the ‘tail’ is gone again.
Up to the 30 second mark, the man and his wings have a shadow.
At 31 sec, somebody’s shoulder blocks the camera’s view of the shadow.
At 32 sec, the shoulder is gone, and so is the shadow...and the picture is suddenly blurry.
