The last major upgrade to the primary rail system occurred in 2002, when the narrow-gauge track was lengthened to 20,379 ft (6,212 m). The HHSTT currently holds the world land speed record for rocket sleds set in April 2003, at Mach 8.6, or 9,465 feet per second (2,885 meters per second), or 6,453.409 miles per hour (10,385.755 kilometres per ...
Sliding pads, called "slippers", are curved around the head of the rails to prevent the sled from flying off the track. Air cushions and magnetic levitation have also been used as alternatives, with potential benefits including reduced sled vibration. A rocket sled holds the land-based speed record for a vehicle, at Mach 8.5. [3]
It was a United States Air Force (USAF) launch complex with a rocket research track that launched a rocket ejection seat from a supersonic sled. The track's 12,000 ft (3,700 m) "of continuously welded, heavy-duty crane-rails aligned to within plus or minus one-tenth inch tolerance [was] the longest" in the US (cf. the shorter 1954 Holloman ...

"We’re just college students who have homework and dishes and groceries to do, and we just sent a rocket to space. We broke the world record and sent a rocket higher than any [amateur] ever has.”
A rocket sled launch, also known as ground-based launch assist, catapult launch assist, and sky-ramp launch, is a proposed method for launching space vehicles. With this concept the launch vehicle is supported by an eastward pointing rail or maglev track that goes up the side of a mountain while an externally applied force is used to accelerate ...

Eli Lackland Beeding Jr. (December 17, 1928 – December 21, 2013) [1] was a U.S. Air Force captain and rocket test subject. In 1958, a series experiments using a miniature rocket sled began at Holloman AFB under the supervision of Colonel John Stapp and Captain Beeding.
