One of NASA Dryden Flight Research Center's two Beechcraft King Air mission support aircraft showed off its lines over Edwards Air Force Base, CA.

Flying by the snow-covered southern Sierra Nevada mountains, NASA's DC-8 airborne science laboratory conducts a checkout flight for the more than 20specialized science instruments installed on the aircraft prior to departure for the Deep Convective Clouds and Chemistry Mission.

Sierra Nevada Corporation's (SNC) Dream Chaser® spacecraft shown on the runway at NASA's Armstrong Flight Research Center on May 20 preparing for a tow-test.

The modified Dryden Remotely Operated Integrated Drone (DROID) small UAV research aircraft in the foreground is being used as a test bed for further development of autonomous ground collision avoidance system software that was successfully flight-tested on the Air Force F-16D behind it at NASA Dryden in 2010.

NASA engineers say the X-57 Maxwell all-electric airplane, as shown in this artist’s rendering, is expected to validate research that electric propulsion technologies can achieve a five-time reduction in energy use, eliminate carbon emissions and considerably reduce community noise.

The ER-2 aircraft arrives at Ellington Field in Houston to prepare for NASA’s Studies of Emissions, Atmospheric Composition, Clouds, and Climate Coupling by Regional Surveys -- SEAC4RS for short – Earth science mission.

NASA Dryden Flight Research Center's new in-house designed Propulsion Flight Test Fixture (PFTF) is an airborne engine test facility that allows engineers to glean actual flight data on small experimental engines that would otherwise have to be gathered from traditional wind tunnels, ground test stands or laboratory setups.

F-15D Eagle Follows OLYMPEX Science Mission

How differential deflection of the inboard and outboard leading-edge flaps affected the handling qualities of this modified F/A-18A was evaluated during the first check flight in the Active Aeroelastic Wing (AAW) project at NASA's Dryden Flight Research Center.

NASA’s C-20A with Generation Orbit’s hypersonic testbed attached is chased by the agency’s F-18 jet for safety and photography.

NASA Global Hawk 872 carried the Hawkeye sensors on wing-mounted pylons during a checkout flight of instruments for the 2014 ATTREX mission over the western Pacific Ocean.

The remotely piloted Ikhana flew a checkout mission for an Air Collision Avoidance System project.

A T-38C from the Air Force Test Pilot School served as a target for NASA’s schlieren imaging system.

A U.S. Air Force Test Pilot School T-38 is captured, using a special filtered camera on the ground, flying in front of the sun. Shockwaves are seen beginning to form as the vehicle transitions from a subsonic speed to supersonic.
