The O-46, which entered service in 1936, was overtaken by the need for observation aircraft to be nimble, small and able to use rudimentary airfields. The O-46 was a large, lumbering aircraft that would have been a sitting duck for fighters. A few were in the Philippines at the start of the Pacific war in 1941 but mostly they were US based with the Air National Guard or on mundane utility work.

At the time, many pilots qualified for deck landing on USS Sable and USS Wolverine, which were side paddle-wheel aircraft carriers. Quite a few aircraft were lost in Lake Michigan, and this Wildcat was recovered in 1988.

On display at the Cradle of Aviation Museum. This aircraft was built as a CV-340-68 and was converted to a CV-440. It served with a number of airlines, and with the Luftwaffe as 12+01. Its last civil registration was N24AT. This nose section has been painted to represent a Lufthansa Convairliner. Lufthansa flew four CV-340s and seven CV-440s on short-haul routes, inaugurating its domestic services on April 1, 1955.

One of five "Intruder II" development aircraft built, on display at the Cradle of Aviation Museum. Intended as an upgrade for the successful A-6E, it was to feature the GE F404 turbofan, new avionics and two more wing pylons, bringing the number of stations to seven. The first flight of the A-6F was on Aug. 2, 1987. The A-6F program got cancelled when the US Navy preferred the A-12 Avenger II, which in turn was cancelled.

On display at the Cradle of Aviation Museum. In the aviation boom following Lindbergh's transatlantic flight, the Robin became popular with its enclosed cabin and monoplane design. Designed in 1927 in Garden City before production shifted to St. Louis, Robins made several historic flights including a world endurance record of over 647 hours with refuelling in 1930. This Robin is equipped with EDO model 2880 floats.
