OOPS!! When in college I saw a film of a guy starting a plane. In the right seat was a gorgeous woman. Not a pilot. He told her to hold the toe brakes then got out. The plane started on the first turn. She let go of one of the brakes and the thing went round in circles tearing through other planes. When he tried to get into the plane run ammock he fell and got smacked by the tailwheel right in the head. Gross. A large van smacked into it to stop it. I doubt she ever flew again. Must havebeen 15 people trying to stop this thjing. But it didn't take off.
Peace
