— If there is single type of aircraft that is associated with both U.S. human spaceflight and the research that puts the first "A" in National Aeronautics and Space Administration, it is the Northrop T-38 "Talon." Now, the public can own an artifact from one or both roles that the supersonic jet serves for NASA.

MotoArt on Thursday (April 16) is releasing its latest, limited edition "PlaneTags," luggage tag-inspired mementos made out of the authentic skin of retired aircraft. This time, there are a pair of donors — a T-38 that was flown in support of NASA atmospheric research and another that was used to train astronauts.

"Together, they tell the complete story of the T-38 at NASA," MotoArt described on its website.

Referred to by its NASA tail number, N864NA (or NASA 864) was originally built for use by the U.S. Air Force and supported advanced weapons training. In 2005, it was assigned to the space agency's Dryden Flight Research Center (today, Armstrong Flight Research Center) in northern California, where it was flown in support of aeronautics research.

Kelly Latimer, who later went on to earn her commercial astronaut wings flying Virgin Galactic's SpaceShipTwo on three suborbital spaceflights (to date), was one of the test pilots who flew NASA 864.

The aircraft's final flight was not under its own power, but aboard NASA's Super Guppy cargo freighter in 2013, when it was delivered to El Paso, Texas to serve as a parts donor for other T-38 jets in NASA's service.

N910NA (NASA 910) was built in 1965 and entered NASA's fleet at Ellington Field (today Ellington Air and Space Port) in Houston, Texas in 1978. As one of the jets available to the astronauts to fly, NASA 910 was used to familiarize and keep current space-bound crew members with working in high-pressure environments.

The jet may have also been used a chase plane, tracking the launch or landing of space shuttle, as well as flying astronauts between NASA centers and contractors' facilities across the nation.

One of the many astronauts who flew aboard NASA 910 was Story Musgrave, the only person to fly on all five of the space shuttle orbiters over the course of his six flights into space.

"Many decades ago, she [carried] me to the heavens," wrote Musgrave, captioning a photo of him flying aboard NASA 910, in his 2009 book "The NASA Northrop T-38: Photograhic Art From An Astronaut Pilot."

Both T-38 jets ended their service bearing the same modern livery as NASA's T-38 jets in flight today. Their fuselage had a gloss-white base with blue stripes running along their length.

MotoArt is offering 2,500 PlaneTags cut from NASA 864 (AT-38B) and 4,250 tags out of NASA 910. Examples seen so far include all white, all blue and all black tags, as well as combinations of white and black; white and blue; white and red; and red, white and blue (the latter two presumably from the NASA logo on the tail). The NASA 864 tags include the simplified NASA insignia ("meatball") among their engraved markings; NASA 910 has the NASA logotype ("worm") as it sported later in its flight history.

As with all PlaneTags, each is different based on from where it was cut. The cost per tag will be announced when the T-38 tags go on sale on MotoArts' website at 3:00 p.m. EDT (1900 GMT) on Thursday.

Previous NASA aircraft made into PlaneTags include a Lockheed C-121G "Super Constellation" that was used to prepare the space agency's Gemini and Apollo ground stations; NASA's Learjet Airborne Observatory aircraft; a McDonnell F-101A "Voodoo" used to train astronauts in the 1960s; and NASA's Kuiper Airborne Observatory. MotoArt also created tags from the skin of an SR-71 "Blackbird," a Titan II missile and NASA's space shuttle-era Mobile Launch Platform-2 (MLP-2).
