Bill is one of the best pilots I have ever known. Met him when he was still a kid working in the Hobby Barn in Tucson. I too am in awe of him. I know some guys on the engineering side of UAV that have said great things about him. Chip, not so much.
We have a guy with a Hemple Triplane that he hovers. That's wrong, just wrong!!!
I worked with him overseas. He's got a pretty good sense of humor too, but he can also be pretty crafty in evening the score in the playful "dirty trick" categories

Totally agree hovering a Fokker, of any size, is just plain wrong.
Remember Circus, Circuses TOC?
