Boeing B-47E Stratojet

The Boeing B-47, the world's first swept-wing bomber, made its initial flight on Dec. 17, 1947 and quantity deliveries began in 1951. When production ended in 1957, more than 1,200 Stratojets were serving with the Strategic Air Command at USAF bases throughout the world. By the late 1960s, the B-47 was obsolete and was removed from operational service.

The B-47 normally carried a crew of three--pilot, co-pilot (who operated the tail turret by remote control), and an observer who also served as navigator, bombardier and radar operator. In the RB-47 reconnaissance version, the navigator also operated the camera equipment.
