Boeing B-47A


Boeing B-47A (NACA 150) shown on the ramp near NACA High-Speed Flight Research Station at South Base of Edwards Air Force Base, California, in 1953.

The B-47A Stratojet's wing is mounted high on the fuselage with a sweep back of 36 degrees and a span of 116 feet, with wing vortex generators installed. A two engine pod under each wing, and an additional engine pod at each wing tip using General Electric J-47-GE-23 turbojets. The airplane is fitted with a nose boom for measuring airspeed, altitude, angle-of-attack and angle-of-sideslip, and an optigraph for measuring the movements of target lights on the wing and tail.

F/A-18F Super Hornet


PERSIAN GULF (June 15, 2007) - An F/A-18F Super Hornet, from the "Black Knights" of Strike Fighter Squadron (VFA) 154, lands on Nimitz-class aircraft carrier USS John C. Stennis (CVN 74). This arrested landing marked Stennis' 100,000th trap since it's first initial trap in January 1996. Stennis and Carrier Air Wing 9 are on a scheduled deployment in support of maritime operations. Maritime operations help set the conditions for security and stability in the maritime environment, as well as complement counter-terrorism and security efforts of regional nations.

Space Shuttle Discovery & Hubble


Space Shuttle Discovery's crew witnessed this bright full moon from orbit during a December 1999 mission that included servicing the Hubble Space Telescope (the top of which is seen on the right). To the left is Earth's horizon; the full moon on that day, Dec. 22, was brighter than average because it was full at nearly the same time it was at its closest to the Earth at a time when the Earth was relatively close to the sun.

F-16XL


This in-flight view of NASA's two-seat F-16XL #2 research aircraft clearly shows that the left and right wings are definitely not mirror images of each other. Nevertheless, pilots who have flown the highly modified aircraft at NASA's Dryden Flight Research Center, Edwards, Califronia, state that the asymmetry created by modifications to its left wing for the Supersonic Laminar Flow Control (SLFC) project was easily handled by the F-16XL's flight controls, and that the plane handled well. The unique aircraft flew 45 research missions over a 13-month period in the SLFC program which ended November of 1996. The project demonstrated that laminar or smooth airflow could be achieved over a major portion of a wing at supersonic speeds by use of a suction system. The system drew a small part of the boundary layer air through millions of tiny laser-drilled holes in a titanium "glove" fitted to the upper left wing. Data acquired during the program will be used to develop a design code calibration database which could assist designers in reducing aerodynamic drag of a proposed second-generation supersonic transport.
