A view of the Holloman High Speed Test Track from south to north.

Hold on tight because this video shows a high-speed test at the Holloman Air Force Base in New Mexico that makes us think the Air Force should be designing roller coasters. The sled in this video reaches a dazzling speed of 6,599 miles/hour. That’s Mach 8.6 for the science nerds.


The Holloman High Speed Test Track (HHSTT) is a United States Department of Defense/Air Force aerospace ground test facility located at Holloman Air Force Base in south-central New Mexico. According to the Air Force:

“The Holloman High-Speed Test Track is a 10-mile long, precision-aligned track that provides scientists and engineers a platform from which to conduct their various missions. Tests on the track provide valid data on problems which cannot be solved by other ground test means.”
