In July 1943, 78 years ago, the P-47D-25 Thunderbolt made its first flight. The D-25 was the first P-47 variant to use the bubble top canopy. It was used in the bomber escort role by the USAF and ground attacker role by the RAF, and remained in service with Italy into the 50's. http://pbs.twimg.com/media/E8wacwhX0AQ7UND.jpg
