Good Job JohnnyS ! Thats the aircraft I was looking for!
http://en.wikipedia.org/wiki/XP4Y_Corregidor
1. Twin engines.
2. Monoplane.
3. Was considered to have excellent performance.
4. It was to be built for both the military and civilian market.
5. 200 were ordered.
6. Only 1 was built.
7.It was to be built in a brand new plant.
8. The order was cancelled when a critical component was needed for another aircraft.
9. Two design features of this aircraft showed up in another aircraft by the same manufacturer that was built in large quantities.
You're up JohnnyS!
Thanks, Zip
