A U.S. Air Force Lockheed NC-141A <i>Starlifter</i> (s/n 61-2775) that was used in the NASA Eclipse project as a tow vehicle. The project used a Convair QF-106 interceptor aircraft to simulate a future orbiter, which would be towed to a high altitude and released to fire its own engines and carry a payload into space.
