12. Stits SA-2A Sky Baby. The Stits SA-2A Sky Baby was a homebuilt aircraft designed for the challenge of claiming the title of "The World's Smallest". The aircraft was test flown by Bob Starr on 26 May 1952 at Palm Springs, California. It was retired in October 1952 after 25 hours of flight time.

7. Boeing B-747. In this 1974 NASA Flight Research Center (FRC) photograph, the two chase aircraft, a Learjet and a Cessna T-37, are shown in formation off the right wing tip of the Boeing B-747 jetliner. The two chase aircraft were used to probe the trailing wake vortices generated by the airflow around the wings of the B-747 aircraft. The vortex trail behind the right wing tip was made visible by a smoke generator mounted under the wing of the B-747 aircraft.

6. Blackburn B-20. An unusual prototype British hybrid floatplane/flying boat which sported retracting main and wing floats. First flight 26 March 1940.

5. Bristol Type 138. The Bristol Type 138 High Altitude Monoplane was a British high-altitude research aircraft developed and produced by the Bristol Aeroplane Company during the 1930s. It holds the distinction of setting nine separate altitude world records, the ultimate of these happened during a 2¼-hour flight flown by Flight Lieutenant M.J. Adam, in which he achieved a record altitude, which was later homologated by the Fédération Aéronautique Internationale as having attained a maximum altitude of 53,937 ft (16,440 m).

1. Northrop X-21A. The Northrop X-21A was an experimental aircraft designed to test wings with laminar flow control. It was based on the Douglas WB-66D airframe, with the wing-mounted engines moved to the rear fuselage and making space for air compressors. The aircraft first flew on 18 April 1963 with NASA test pilot Jack Wells at the controls.
