Evening clue. Thanks; Ernie P.
Question: What warbird pilot do I describe?
Clues:
(1) Although he was the top ace from his country, in his conflict, he still remains almost an unknown today.
(2) Quite old for a fighter pilot; perhaps particularly so in his time and place.
(3) Flew a very well known type of aircraft; one almost ubiquitous in its day.
(4) He was the first pilot to shoot down another very well known aircraft.
(5) He was shot down and killed by another ace; an Irish ace.
