The pilot's inadequate preflight planning due to his selection of an unsuitable takeoff area and his failure to maintain clearance from the open hangar door.
Certainly true, If the pilot had uses more "common sense" by taking off in an open area clear of obstructions, hangar etc this would'nt have happened.
I agree with doublesix, I would not want to fly with this individual. Sorry but safety should be the number one priority for every aviator!
Still, glad to see know one was seriously injured
Aviation in itself is not inherently dangerous. But to an even greater degree than the sea, it is terribly unforgiving of any carelessness, incapacity or neglect.
I Rest my case
