Evening clue. Thanks; Ernie P.
Question: What warbird pilot do I describe?
Clues:
- This pilot is noted, not for his score, but for his brilliance.
- In fact, I have found no record of his ever having scored a victory.
- He produced an innovation which had a more profound impact upon the combat arms than might at first be realized.
- His innovation was in daily service for more than forty years in its original form; and is still in use today in adapted forms.
