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]

The following is a list of speed records for various types of vehicles.This list only presents the single greatest speed achieved in each broad record category; for more information on records under variations of test conditions, see the specific article for each record category.
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.
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 ...
