Picture of the Day: October 24Picture of the Day | 0 comments | Print This Post | Email This Post
On October 24, 1968, National Air and Space Administration test pilot Bill Dana was at the controls of the North American X-15 rocket-propelled research aircraft when it made the 199th–and what turned out to be the final–flight of the X-15 program. He was flying the X-15-1, which had been the first of three aircraft to participate in a series of tests that spanned a decade and resulted in major advances for America’s space flight program. In the course of that research, the X-15s spent 18 hours flying above Mach 1, 12 hours above Mach 2, nearly 9 hours above Mach 3, almost 6 hours above Mach 4, one hour above Mach 5 and a few short minutes above Mach 6. The X-15 was hailed by the scientific community as the most successful research aircraft of all time. Painting by Stan Stokes, NASA Help HistoryNet by bookmarking to
