How do I word this question correctly? Was the Bell P63 a missed opportunity in the ground attack role in NW Europe post D-Day? I ask this question because I understand that the P63 was a good low level performer that was apparently sturdy and carried a heavy armament that appears to have been just the ticket for use against ground targets such as vehicles and locomotives. I understand that the P63 was not as versatile as either the P51 or P47, but would relatively small numbers of the P63 have been brought benefits if used purely as a ground attack aircraft?
