Chinhooks have stabilizators, extra-efficient one...so if it can put it's rear end on the roof, he doesn't need to worry about flying somewhere X-direction.... but still..doing that is skillful.... Definetly a cool picture
what are you talking about FlyingBlind??? extra efficient stabilizators??
I think the hardest part would be "seeing" where you put your rear wheels. Maybe somebody talked him in or something.
Once you're on the deck, I'd say its probably like a "one-skid-landing" (where you hold one skid against the slope if the terrain is to steep to land with both skids.....frowned upon by the USFS btw...

) but 90 degrees off....
Looks cool though
PS: Is it me or did he actually break through the roof with his wheels??
