Keep working Hydro Junkie; and here's another clue to help you out. Thanks; Ernie P.
What warbird pilot do I describe?
1. This pilot is, today, almost unknown. Yet he was, in many ways, one of the best there ever was.
2. He was born on a farm.
3. And entered military service at a young age.
4. And originally served, as seems natural, in a cavalry unit.
5. He first saw combat as part of a cavalry unit.
6. He switched his path and became a pilot a couple of years later.
