Mystery Man Flies Past Airbus Plane

A mysterious man flew by pilots flying an Airbus 320....but no one knows how he got there...and no one knows how he flew by them. Pilots of an airbus 320 were preparing to land as they descended through 3500 feet. Suddenly, what looked to be a man whizzed by their airplane. It all happened so fast...the pilots were baffled. further reports confirmed there were no hanggliders or anyone in the area - radar reports even confirmed this. The pilots couldn't see any sort of canopy suspending the man, as if he was hang gliding. What could this have been? The pilots only caught a glimpse of this thing...but said it was a man...if so..what was he doing? Literally flying?... There were no other aircraft in the area he could of jumped from.
