I wonder if it is faked. From the casual and non-repeatable way he threw that ball, I really can't imagine he was able to compensate for thermals and wind like that.
Unfortunately it is so easy to fake videos these days, you really can't trust what you see any more.
Also I have seen players break backboards like that just by jumping-shotting. I wonder what the kinetic energy would be. Especially with that camera being there it was in the last bit. I would imagine that there would be more kinetic force transferred.
But then to quote from the movie
The Lost Skeleton of Cadavera "I'm a scientist, I don't believe in anything. "
