same thing happen to me about 25 years ago. was up flying my cub and there were 2 red tail hawks also flying above my 80 ac. farm.
so I had the great idea to fly up to them. I chop the throttle and floated around them for about 5 min. the engine died and as I floated down one of the hawks atack my plane and road it to the ground. the hawk flew back up to the other hawk and my plane never flew again. my wife name the hawk the red baron. all I can say is curse you red baron. true story
