Evening clue. Thanks; Ernie P.
What warbird do I describe?
Clues:
1. There was only one ever built.
2. It was built by one of four aircraft companies which competed in a competition for a contract to build a new warbird.
3. It was the only one of the four which did not eventually enter production in some form.
4. The other three aircraft were all produced in large numbers.
5. This aircraft was the only multi-engined aircraft produced by the company.
6. And, although it wasn’t selected for production, it was a fast aircraft for the day.
7. Despite this failure, the name of the producing company is one well known to almost everyone on this forum.
8. It was initially produced with a large “greenhouse” cockpit area, intended to provide lots of visibility for its pilot and bombardier.
9. Unfortunately, the high visibility cockpit restricted forward visibility for the pilot.
10. So, the company installed a more standard cockpit area; but performance remained about the same.
