Years ago, I showed up for a flight lesson at HEF early one Saturday morning. There was absolute carnage on the ramp. Four planes were wiped out. A beautiful Lance was clearly sliced up by a propeller. I couldn't figure out how it happened because it was all between seemingly undamaged planes on the ramp and the fence.
When I got to the flight school, I got the story. Apparently, some guys got into one of Colgan's planes (King Air or the like) and got one engine started and managed to spin it around in a circle taking out the neighboring planes. One of the flight school's planes was in the wreckage. Going back out to my car the TV news crew popped up and stuck a microphone in my face and wanted to know why the tower didn't see it. I pointed out that given the number of beer cans around the scene, that it likely happened after the bars closed and the tower closes at 11PM.
Later old man Colgan is interviewed on TV. "Has to be an inside job. These things aren't easy to start. Unless you know how. Then it's easy." I pointed out to others that there was probably this book inside the cockpit that had some instructions on it.
