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.

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.

Originally USAF 55-2961 and designated YF-104A.

Piloted rocket-powered "lifting body" test vehicle. Flew from 06.70 to 12.72 reaching supersonic speeds and over 70,000 feet altitude.

NASA Space Shuttle Carrier Aircraft, with test shuttle 'Enterprise' during Paris le Bourget Air show 1983. .

The sole SR-71B for NASA is seen here at the platform of NASA Dryden Flight Research Center at Edwards AFB (CA). Unfortunately, the full back light did not create the very best picture... The trainer was prepared for a familiarisation flight, its first official research flight for Dryden DFRC took place some two years later, on 9 March 1993. NASA 831 is former USAF 64-17956 and was delivered to the NASA on 25 July 1991 after a long USAF service that started in November 1965. After its NASA career the aircraft was dismantled and delivered to the Kalamazoo (MI) Air Zoo in March 2003 for perservation.

NASA's WB-57F, in this case NASA 928, on short final to runway 32 at March ARB. It's previous military serial was 63-13298

Another incredible sight at Pima.

With NASA since 1986. Used as a flying laboratory.

This Gulfstream II was modified to serve as a Shuttle Training Aircraft (STA). Its cockpit was designed to closely resemble the flight deck of the Space Shuttle and the aircraft could be used to simulate the flight characteristics of the Space Shuttle during re-entry and landing after an orbital mission. The aircraft joined the collections of the US Space & Rocket Center in 2017.
