The US Navy had 2 flying aircraft carriers – zeppelins, which launched and recovered biplanes using a skyhook. The USS Akron and the USS Macon The Sparrowhawk aircraft had their landing gear removed and had to hit a hook that slung them in a corner in and out of the ship. No arrestor cable, no launch rail and a better safety record than current carriers. The end of the airship era ended the project, unfortunately.
