A life's (fatal) lesson on how NOT to maintain magnetos

The original '9 Oh 9' had a charmed life during WW2. Went on 140 bombing missions without loss of a crewman. Well beyond the norm in those dangerous days.
The replica plane also had an interesting history, built too late to be a part of WW2, was later flown by remote control through a couple of nuclear testing episodes to gather data. That got the plane so hot it was parked for years. It was said to be possibly the most complete and original example of a B17 in existence. The loss of that plane is not greater than the loss of life in the crash, but the loss of that plane was also huge.
