NASA Dryden's new in-house designed Propulsion Flight Test Fixture (PFTF) flew mated to a specially-equipped supersonic F-15B research aircraft during December 2001 and January 2002.

NASA's F-15B from the Dryden Flight Research Center flew in the supersonic shockwave of a modified U.S. Navy F-5E jet in support of the Shaped Sonic Boom Demonstration (SSBD) project. On Aug. 27, 2003, the F-5 SSBD aircraft demonstrated a method to reduce
