We had bad thunderstorms in Texas, including a tornado that touched down on the runway at the airport I'm at. I'm in an open T-Hangar. No damage to the t-hangar but my not so smart hangar neighbor can't tie his stupid Cessna 150 down properly. My plane was anchored to the ground, didn't move an inch. His Cessna literally flew into mine because he doesn't choke his plane and ties it down way too loose. So, his tail hit my aileron and possibly more - it's dark so I'll see the full damage tomorrow. Where do I go from here? Do I sue him? Do I tell the insurance? Airport? Never met this guy but he's been ****ing me off for months by how he parks and "ties down" his damn airplane. Others on the field apparently told him several times to tie it down properly.
