Last active in May 1993, seen here at NASA storage. Aircraft participated in many test programs one of which was HIDEC and is marked as such here.

The wedge-shaped vertical stabilizer necessary for directional stability, upper speed brakes and a small tail-skid in retracted position is visible on the first X-15 on display at NASM. Just three of these hypersonic aircraft were built, and only 12 pilots flew them including Neil Armstrong for a total of 199 flights from 1959-68. The X-15 set the world's unofficial speed record of Mach 6.70 with Flight No. 2-53-97, and an altitude record of 354,200 ft. with Flight No. 3-22-36. The second X-15 is displayed at NMUSAF. The third X-15 was lost on 15 Nov 1967 on Flight 3-65-97 in a fatal accident.

Delivered to the USAF as 65-10353. Assigned to NASA asa NASA 911. Registered as N911NA in 1969 then N821NA by 1984 and N967NA in 1995. Converted to a T-38N. Still operational in 2022.

Delivered to the US Army as 64-13628. To NASA Langley Research Center, Langley Field, VA as NASA 542 in 1973 then to NASA Ames Research Center, NAS Moffett Field, CA as NASA 734/N734NA in 1978 and NASA Kennedy Space Center, FL as N417NA in 1993. Sold to a private owner in 2011.

Cancelled order for Braniff as N7078. Delivered to the FAA as N113 in 1961. Reregistered as N23 in 1977. To NASA as N1697V in 1981. Reregistered as N833NA in 1983. Destroyed in a controlled crash at Edwards AFB on 01/12/1984.

Ex Luftwaffe RF-104G 24+64. This Starfighter arrived at the NASA Dryden Flight Research Center on 2 July 1975 and remained in service up to October 1993. It is now preserved at Edwards.

T-38A 65-10353 became N911NA with NASA Johnson on 10 February 1966. It became N821NA and arrived at NASA Dryden at 28 September 1972. It was converted to T-38N in early 1988. Later transferred to NASA Johnson Space Center on 12 October 1994. Reregistered to N967NA in early 1995.

This weird looking x-wing was delivered to Dryden as N805NA with code NASA 838 on 12 March 1979. The Lockheed Folding Wing was on and off active and stored at Dryden but eventually withdrawn from use and transferred to the NASA Ames Research Center museum in February 1998.

This 9th built F-15A arrived at NASA on 5 January 1976. It was a former 6512th Test Squadron aircraft at nearby Edwards AFB (CA) up to November 1975. It was used by the USAF for spinning, high angle-of-attack and fuel systems development trials. After delivery to Dryden it became part of the Highly Integrated Digital Electronic Control (HIDEC) flight research program. Up to July 2001 the Eagle was on loan from the USAF. In that month it was reregistered to N835NA/835. From February 2006 is was reported at stored. GThis status was at least up to late 2010.

This Starfighter was factory-fresh handed over to NASA on 19 July 1963. It arrived at Dryden on 19 August 1963. It stayed operational up to 1990, was stored at Edwards until October 1992 and was then preserved at the visitors center of Embry Riddle Aeronautical University Prescott (AZ)

First flown in 1967, became N8351Y and was assigned to NASA Dryden's Research Operations Division for Program Support on 5 June 1967. The Piper was among other missions, used for validating remotely piloted research vehicles in addition to research into General Aviation aircraft. It was withdrawn from use and popped up as an instructional airframe at Reedley (CA) Aviation Maintenance Technology Dept at Reedley College on 19 May 1995.

Former USAF 65-10357, delivered to NASA Ames in December 1972, did not receive a NASA registration as it was assigned to NASA Dryden on 16 March 1973. Reregistered to N915NA at NASA Ames on 22 January 1990, and later to N722NA and N717NA at Ames, converted to T-38N in October 1997 and delivered to NASA Johnson as N966NA.
