The Avro 707 is an experimental aircraft designed and produced by the British aircraft manufacturer Avro.
The Scaled Composites Model 281 Proteus is a tandem-wing high-altitude long-endurance aircraft designed by Burt Rutan to investigate the use of aircraft as high-altitude telecommunications relays. The Proteus is a multi-mission vehicle able to carry various payloads on a ventral pylon. The Proteus has an extremely efficient design and can orbit a point at over 19,800 m for more than 18 hours. It is currently owned by Northrop Grumman.
The NASA M2-F1 is a lightweight, unpowered prototype aircraft, developed to flight-test the wingless lifting body concept. Its unusual appearance earned it the nickname "flying bathtub" and was designated the M2-F1, the M referring to "manned", and F referring to "flight" version. In 1962, NASA Dryden management approved a program to build a lightweight, unpowered lifting-body prototype. It featured a plywood shell placed over a tubular steel frame crafted at Dryden. Construction was completed in 1963.
The Avioane Craiova IAR-93 Vultur (Eagle) is a twinjet, subsonic, close support, ground attack and tactical reconnaissance aircraft with secondary capability as low level interceptor. Built as single-seat main attack version or combat capable two-seat version for advanced flying and weapon training, it was developed in 1970s by Romania and Yugoslavia to become more independent from Soviet equipment. The Romanian aircraft were built by I.R.Av. Craiova as IAR-93, and its Yugoslav counterpart by Soko as the Soko J-22 Orao. For Romania, the IAR-93 was intended to replace MiG-15s and MiG-17s in the fighter-bomber role.
The X-26 Frigate is the longest-lived of the X-plane programs. The program included the X-26A Frigate sailplane and the motorized X-26B Quiet Thruster versions: QT-2, QT-2PC, and QT-2PCII. All were based on the Schweizer SGS 2-32 sailplane.
The Lockheed YO-3 Quiet Star is an American single-engined, propeller-driven aircraft that was developed for battlefield observation during the Vietnam War. Designed to be as quiet as possible, it was intended to observe troop movements in near-silence during the hours of darkness.
The Sikorsky S-69 is an American experimental compound helicopter developed by Sikorsky Aircraft as the demonstrator of the co-axial Advancing Blade Concept (ABC) with United States Army and NASA funding.

The Ling-Temco-Vought XQM-93 was a remotely piloted aircraft developed in the United States in the late 1960s and early 1970s for use as a communications relay in the Vietnam War. A prototype flew in 1970, but the program was abandoned without producing a service-ready aircraft.
A high-altitude platform station, also known as atmospheric satellite, is a long endurance, high altitude aircraft able to offer observation or communication services similarly to artificial satellites. Mostly unmanned aerial vehicles (UAVs), they remain aloft through atmospheric lift, either aerodynamic like airplanes, or aerostatic like airships or balloons. High-altitude long endurance (HALE) military drones can fly above 60,000 ft over 32 hours, while civil HAPS are radio stations at an altitude of 20 to 50 km above waypoints, for weeks.
The Ryan YQM-98 R-Tern was a developmental aerial reconnaissance drone developed by Ryan Aeronautical. It could take off and land from a runway like a manned aircraft, and operate at high altitudes for up to 24 hours to perform surveillance, communications relay, or atmospheric sampling.
The LTV L450F, also known as the L45ØF, was a prototype quiet reconnaissance aircraft, developed by Ling-Temco-Vought in the late 1960s for use in the Vietnam War by the United States. Based on the airframe of a Schweizer 2-32 sailplane, the aircraft flew in 1970, and was developed into the XQM-93 reconnaissance drone before the project was cancelled.
The AVE Mizar was a roadable aircraft built between 1971 and 1973 by Advanced Vehicle Engineers (AVE) of Van Nuys, Los Angeles, California. The company was started by Henry Smolinski and Harold Blake, both graduates of Northrop Institute of Technology's aeronautical engineering school.
