1946: (featured image) Convair’s B-36 “Peacemaker” – the world’s first intercontinental bomber – makes its first flight. The B-36’s massive 230-ft. wingspan makes it the largest of any combat aircraft ever built, and the joint jet- and piston-powered aircraft could deliver its nuclear payload 10,000 miles un-refueled. The Peacemaker’s tenure with Strategic Air Command only lasted until 1955, however, when it was replaced with the B-52 “Stratofortress” bomber still in use today.
