Afternoon clue. Thanks; Ernie P.
What warbird do I describe?
Clues:
1. The genesis of this aircraft was an attempt to follow the research and designs of a noted aerodynamic pioneer.
2. It was designed by another noted, and very successful, aerodynamicist.
3. It set multiple world records when it was introduced.
4. Yet it was actually used for a rather short time.
5. And, it never entered combat.
6. It was the first of its type to hold an outright speed record.
