Hurricane Supersonic Research Site
The Hurricane Supersonic Research Site (HSRS) on Hurricane Mesa was a USAF launch complex with a rocket research track that launched a rocket ejection seat from a supersonic sled. The track's "of continuously welded, heavy-duty crane-rails aligned to within plus or minus one-tenth inch tolerance () the longest" in the US (cf. the shorter 1954 Holloman Rocket Sled). Coleman Engineering Company was contracted for $2 million in June 1954 and constructed the Supersonic Military Air Research Track (SMART), mechanical arresting gear (water brakes with 34 tons of force), retro rockets, and photographic/telemetering facilities. Coleman was also contracted for operations on November 30, 1955, and achieved a "world land speed record () a 9,400-pound sled rocketing down the track at 1,800 miles per hour." The numerous test facilities included a powered comparator for high-speed motion pictures, a 1956 IBM 706 computer, and 1960 Bendix G-15 computer. Control of the site transferred from Indian Springs Air Force Base on November 6, 1957, and from Wright-Patterson AFB to Edwards AFB on March 9, 1962—the base was placed on standby in December 1961, and was closed on June 20, 1963.
The Formerly Used Defense Site (J08UT0026) initially transferred to Stanley Aviation and was leased to Sacol, Inc. on May 21, 1965.〔
