Built for USAF as B-57B 52-1576. Later transferred to NASA and modified for research programmes including into gusting.

Later reregistered N428NA when NASA gave up using its own serials.

Built as a 377 and delivered to Pan American World Airways in September 1949 as N1038V. Initially it was named Clipper Constitution, later renamed Clipper Hotspur. Withdrawn from use and stored at New York in 1960. To Boeing, (August 1960), Lee Mansdorf & Co. (October 1960) and Aero Spacelines (1963), where it was converted to a 377SGT. By August 1965 it was registered N1038V again. In September 1965, the aircraft was involved in an incident at/near Mojave (CA); the airframe failed in-flight (while cruising). The factors included separation in flight and damage was substantial. The aircraft was able to make an emergency landing and there were no fatalities. NASA have had 2 377's registered as N940NS, the other one being c/n 16724.

This unique DHC-5 Quiet Short-Haul Research Aircraft (QSRA) variant was a NASA research aircraft modified to study and develop Short Take Off and Landing (STOL) technology. The QSRA was among other things modified with 4 Lycoming F102 turbofan engines. It first flew in this configuration in 1978. This aircraft even performed a landing and takeoff on the US aircraft carrier USS Kitty Hawk, (of course) requiring neither arresting gear nor catapult launch. The techniques learned from this Buffalo stood model for the Boeing YC-14/C-17 programme and is now preserved at Moffett Museum's airpark (CA)

NASA 28 departing on a grey day - taken at some distance. This was deployed to Mildenhall on only a few occasions. [Close inspection only reveals 28 on the fuselage and some sources give the identity as NASA 928 or even 63-13298. The registration N928NA was issued about ten years after this image in June 2015.]

This Super Guppy had just departed Davis Monthan and I wish I knew what it was transporting. It had been in the area several days. It was an amazing sight.

Four-engined experimental tilt-wing aircraft used in a joint NASA/USAF research program.

The first of the three X-15's - also referred to as the X-15-1. Launched from the B-52 carriers, this rocket-powered research aircraft reached over Mach 5 and 50 miles altitude. The pilots of those particular flights being classified by the Americans as astronauts.

NASA acquired this Lancair in 2001 for the Small Aircraft Transportation System project based at the Langley Research Center in Hampton, Virginia.

The sole survivor of five XC-142A tilt-wing test aircraft built in the mid 1960's. Allocated USAF serial 62-5924.
