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]

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 ...
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 ...
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.
The record-shattering rocket launch was only about 3.8 miles short of the altitude allowed for amateur rocketry, but the students are hoping to break new records in the club’s future.
The first run on the rocket sled took place on 30 April 1947 with ballast. The sled ran off the tracks. The first human run took place the following December. Instrumentation on all the early runs was in the developmental stage, and it was not until August 1948 that it was adequate to begin recording.
