Video: The Boeing B-29 Superfortress heavy bombers were one of the biggest and deadliest aircraft used during World War II. They were the bombers used to drop the atomic bomb and were also used during the Korean war. Here's a video from Bryce Richert showing how the gun turret system worked on the B-29. Like the guy in the video said, it's basically Robocop. Which is very impressive considering the B-29's first flight was in 1942.
