Project: Quiet Spike
NASA’s F-15B testbed aircraft went through pre-flight checks before performing the first flight of the Quiet Spike project. The first flight was performed for evaluation purposes, and the spike was not extended. The Quiet Spike was developed as a means of controlling and reducing the sonic boom caused by an aircraft ‘breaking’ the sound barrier.August 10, 2006NASA Photo / Tony Landis› Quiet Spike Project Description
