I was almost hit twice one week ( about three weeks ago). One was a guy trying to solo (I think) An instructor was next to him in case anything went wrong. I was up high messing around while he tried to bring it in, after two or three go arounds, he came in and touched down, but bounced. He decided to throttle up and go around again. Without even looking where its headed (into the pilots box), he starts to throttled up, even though its aimed at my legs. He pulls up like in a takeoff. All of this is less than 8-10 feet away. Now its aimed at my chest. Instructor grabbed the radio and nosed it straight in from 3 feet at near stall speed. No damage. Supposedly he crashed into the fence behind the pilot box the next day. Then during the week I went flying and had just landed when one pilot made a fly by and throttled up, barely clearing the fence between the runway and pit box and headed right for my truck, where I was sitting. I gotta say, I've never been that close to a engine that was running. He pulled vertical flew up over and crashed into the barb wire fence on the property line. Supposedly he had crashed two planes before I got there that day. I left after that, and almost got hit by an 18-wheeler that ran a red light. I felt like locking myself indoors.
