Flying aircraft carriers sound like fantasy, something you’d only see in a crappy Marvel movie. But they’re real. Or rather, were real. In the 1930s, the United States made two plane-carrying airships. This video has the remains of one, the USS Macon, lying at the depths of the Pacific Ocean.
The Macon and her sister ship, the USS Akron, were huge vessels, less than 20 feet shorter than the ill-fated, hydrogen-filled Hindenburg. But the Macon and the Akron were inherently safer, borne aloft by less-flammable helium, and propelled by eight 12-cylinder Maybach engines. The engines themselves could rotate downwards and backwards, enabling a modicum of thrust-vectoring control.
