The Boeing B-29 Superfotress was the backbone of the Pacific bomber fleet during World War Two. So why not make even better. Enter the B-50. And then even bigger, faster and better as the B-54. With the Air Force planning for production of 30 planes per month the contract was abruptly canceled in 1949. Why? Three reasons: the new SAC commander Curtis LeMay, the colossal B-36 Peacemaker and fortunately for Boeing, the B-52 Stratofortress.
