gear up
here's a true story - I had a hangar on Boeing Field, Seattle. My neighbors were a couple of older guys with a twin engined airplane. One day I came down to the field and they were repairing the plane - on jacks. They had landed it without lowering the landing gear. That being bad enough, a little later I came down and they were sort of looking sad - I asked why, they said that one of them had been cleared for takeoff in a small single engined airplane (one that required a person in front to turn the propeller to start the engine) and the plane stalled and the engine stopped. The man actually got out of the plane and turned the propeller over by hand to restart the engine. It started - but he had left the throttle open and the plane (without pilot aboard) had sped across the field and crashed into a fence.
I shook my head in wonder and went into my hangar.
true story.
