A buddy of mine used to fly "Ag Cats" if I remember the name correctly. It was a biplane, with a big radial in it. If I remember there was a regular and turbo or supercharged version.

This friend was a risk taker. He ended up hitting a high voltage power line at the end of a run. One wheel went over, one went under the power line. These Ag Cats have a NASCAR like roll cage. He said the next thing he remembers is walking down a dirt road next to the field, in a daze. He was very lucky. The plane was totaled.
