must admit, the first time i watched it i assumed it was a tail strike. for some reason i thought the hangar was to the left. but i think you're right, think right hand side of disc hit the hangar. cameraman had back to hangar whilst filming i think.
what a mong pilot quite surprised everyone walked away.
The guy claimed that the pax in the left hand seat inadvertantly used their 'knee' to apply pressure to the cyclic and that is what caused the movement towards the hangar....except the video doesn't show any movement towards the hangar!!
