Thats pathetic smallpiece. I cant believe you posted an image of a damaged wing that probally cost the confidence of a student pilot not to mention SF alot of money to repair. Its people like you who ruin GA.
Get a life!!!!.
Actually it would still cost SF money whether or not this photo was published. The pilot who did this was actually a PPL (ex) hirer and his confidence was probably shattered when he was asked to leave and quite rightly so. There is a grass taxiway which avoids the area of the narrow gate where this incident happen. Perhaps if clear instructions/proper checkouts were performed by the school as to where it is safe to taxi this wouldn't happen.
Smallpiece is not the sort of person who ruins GA, it's the other people who refuse to acknowledge problems within GA and do something about them, just saying a flight school has your support does not change past events or excuse incident/accidents.
