In 1950, the Airphibian became the first roadworthy aircraft to receive a type certificate from the CAA. It was a technical success but the inherent compromises necessary in the design meant that the performance specs were disappointing. This very interesting piece of aviation history is on display at the NASM Udvar-Hazy Center.

The H-19/HRS-1 was the first practical single-rotor utility helicopter and the first in Sikorsky's successful S-55 series. The centre-of-gravity problems of earlier models were solved by shifting the engine to the front and the passenger compartment to beneath the rotor hub. Other innovations included offset-flapping hinges and hydraulically boosted irreversible controls. This example is now on display at the Steven F. Udvar-Hazy Center of the Smithsonian NASM.

This SR-71 spent 24 years on active USAF service accumulating 2,801 hours of flight time. On 6th March, 1990 its service career ended with a record-setting flight, flying from Los Angeles to Washington DC in 1 hour, 4 minutes and 20 seconds, averaging a speed of 3,418 kph (2,124 mph). After landing at Dulles the SR-71 was handed over to the NASM and is now on display at the Udvar-Hazy Center.

This aircraft is one of eighteen airplanes that were specifically designed by Huff-Daland to perform aerial crop dusting. C.E. Woolman took over the company in 1928 and renamed it Delta Air Service (the forerunner of Delta Air Lines) to reflect the addition of mail and passenger service in Travel Airs. The remains of two of the original 18 Dusters stayed in storage until 1967 when Delta Air Lines selected one of them for restoration, unfortunately it's registration number is unknown.

This shot needed a loooong time waiting for the large floor area to be free of people - finally! This P-26 was operated by the Army Air Corps from 1934 until being transferred to the Panama Canal Department Air Force in 1938. It was given to Guatemala in 1942 and flew in their AF until 1954 and subsequent donation to the Smithsonian NASM in 1957.

This PT-13 as 42-17724 was based at Moton Field, Alabama during WWII and used to train the pilots that became known as the Tuskegee Airmen. The 'Spirit of Tuskeegee' is on temporary display at the NASM Udvar-Hazy Center until ready to be accepted by the Museum of African American History and Culture (NMAAHC).

'Plain Jane' was a primary training aircraft belonging to the Roosevelt Aviation School in the 1930s based at Roosevelt Field, Long Island. Now she is on display at the NASM Udvar-Hazy Center.

The Messenger is the smallest manned aircraft ever used by the US Army and this example, the last remaining, is on display at the Udvar-Hazy Center. It was originally a Sperry Sport Plane but converted to M-1 configuration in the early 1960s. It is on display wearing the markings of the aircraft used in 1924 to make the first successful airship hook on and release in the air.
