British Carrier Developments
One other development that the Brits can claim:-
Imitially,the USN pilots had a hard time getting the F4U Corsair aboard safely due to the practice of "straight-in" approaches; the pilots couldn't see over the nose. This was why, initially, many F4Us were assigned to the Marines for shore-based operations. When some were alocated to the Fleet Air Arm, someone figured out that a curved approach improved visibility almost on to the deck. The USN adopted this shortly afterwards.
I have a good friend who flew Corsairs in the Korean conflict off a carrier. He told me that by then the U.S. Navy had reverted to teaching the old method of approach which he felt very uncomfortable with. Once deployed, he remembered the British way and started using it.He was chewed out for it, but soon everyone picked it up and safer landings resulted.
