NASA F-15B #836 in flight with Quiet Spike attached. The project sought to verify the structural integrity of the multi-segmented, articulating spike attachment designed to reduce and control a sonic boom. Made of advanced composite materials, the Quiet Spike weighed some 470 pounds and extended from 14 feet in subsonic flight to 24 feet in supersonic flight.October 3, 2006NASA Photo / Jim Ross› Quiet Spike Project Description
