One related point: Before the successful testing of the angled deck, the USN experimented with all kinds of other ways of operating high-performance aircraft at sea, including the tailless, high-alpha F7U and F4D, the swing-wing Grumman Jaguar, VTOL tail-sitters and the F2Y Sea Dart. All such things became rapidly extinct once the steam cat, angled deck and mirror landing system were proven to work.
