C-17 makes first flight on synthetic fuel blend
A C-17 Globemaster III taxis past the control tower at Edwards Air Force Base, Calif., on Oct. 19, 2007. The early-morning flight marked the first flight of the C-17 using a Fischer-Tropsch synthetic fuel blend in one of its engines. All four engines ran the fuel blend in subsequent tests.
