O.K., after looking at it again and then going to Google for a search it appears to be a well done bogus event. Excellent editing. Here's a comment from a R/C forum I found:
"I know the pilot of this RC model. His name is Bill Hempel and his father
owns The Hobby Barn. If you ever did RC, then chances are good you ordered
from him at one time. I've known Billy since he was 10 and he's been flying
for at least 30 years. He started flying before he was 10. He is one of the
best RC pilots in the world and works for an agency that trains UAV pilots.
He can fly anything with and without wings. This video was shot at the local
RC field, about three miles from my house.
