The Bell X-1 is a rocket engine–powered aircraft, designated originally as the XS-1, and was a joint National Advisory Committee for Aeronautics–U.S. Army Air Forces–U.S. Air Force supersonic research project built by Bell Aircraft. Conceived during 1944 and designed and built in 1945, it achieved a speed of nearly 1,000 miles per hour in 1948. A derivative of this same design, the Bell X-1A, having greater fuel capacity and hence longer rocket burning time, exceeded 1,600 miles per hour in 1954. The X-1 aircraft #46-062, nicknamed Glamorous Glennis and flown by Chuck Yeager, was the first piloted airplane to exceed the speed of sound in level flight and was the first of the X-planes, a series of American experimental rocket planes designed for testing new technologies.
The North American X-15 is a hypersonic rocket-powered aircraft. It was operated by the United States Air Force and the National Aeronautics and Space Administration as part of the X-plane series of experimental aircraft. The X-15 set speed and altitude records in the 1960s, reaching the edge of outer space and returning with valuable data used in aircraft and spacecraft design. The X-15's highest speed, 4,520 miles per hour, was achieved on 3 October 1967, when William J. Knight flew at Mach 6.7 at an altitude of 102,100 feet (31,120 m), or 19.34 miles. This set the official world record for the highest speed ever recorded by a crewed, powered aircraft, which remains unbroken.
SpaceShipOne is an experimental air-launched rocket-powered aircraft with sub-orbital spaceflight capability at speeds of up to 3,000 ft/s, using a hybrid rocket motor. The design features a unique "feathering" atmospheric reentry system where the rear half of the wing and the twin tail booms folds 70 degrees upward along a hinge running the length of the wing; this increases drag while retaining stability. SpaceShipOne completed the first crewed private spaceflight in 2004. That same year, it won the US$10 million Ansari X Prize and was immediately retired from active service. Its mother ship was named "White Knight". Both craft were developed and flown by Mojave Aerospace Ventures, which was a joint venture between Paul Allen and Scaled Composites, Burt Rutan's aviation company. Allen provided the funding of approximately US$25 million.
The NASA X-43 was an experimental unmanned hypersonic aircraft with multiple planned scale variations meant to test various aspects of hypersonic flight. It was part of the X-plane series and specifically of NASA's Hyper-X program. It set several airspeed records for jet aircraft. The X-43 is the fastest jet-powered aircraft on record at approximately Mach 9.6.
The Scaled Composites Model 318 White Knight is a jet-powered carrier aircraft that was used to launch its companion SpaceShipOne, an experimental spaceplane. The White Knight and SpaceShipOne were designed by Burt Rutan and manufactured by Scaled Composites, a private company founded by Rutan in 1982. On three separate flights in 2004, White Knight conducted SpaceShipOne into flight, and SpaceShipOne then performed a sub-orbital spaceflight, becoming the first private craft to reach space.
Peter Siebold is a member of the Scaled Composites astronaut team. He is their Director of Flight Operations, and was one of the test pilots for SpaceShipOne and SpaceShipTwo, the experimental spaceplanes developed by the company. On April 8, 2004, Siebold piloted the second powered test flight of SpaceShipOne, flight 13P, which reached a top speed of Mach 1.6 and an altitude of 32.0 kilometres (105,000 ft). On October 31, 2014, Siebold and Michael Alsbury were piloting the SpaceShipTwo VSS Enterprise on flight PF04, when the craft came apart in mid-air and then crashed, killing Alsbury and injuring Siebold.
Flight 15P of SpaceShipOne (X0) was the first privately funded human spaceflight. It took place on June 21, 2004. It was the fourth powered test flight of the Tier One program, the previous three test flights having reached much lower altitudes. The flight carried only its pilot, Mike Melvill, who thus became the first non-governmental astronaut.
Tier One was a Scaled Composites' 1990s–2004 program of suborbital human spaceflight using the reusable spacecraft SpaceShipOne and its launcher White Knight. The craft was designed by Burt Rutan, and the project was funded 20 million US Dollars by Paul Allen. In 2004 it made the first privately funded human spaceflight and won the 10 million US Dollars Ansari X Prize for the first non-governmental reusable crewed spacecraft.
Flight 11P of SpaceShipOne was its eighth independent flight, its first powered flight, and the first privately funded crewed flight to reach supersonic speeds. It occurred on December 17, 2003.
Flight 13P of SpaceShipOne was its second powered flight, which occurred on April 8, 2004. The pilot was Peter Siebold.
Flight 16P of SpaceShipOne was a spaceflight in the Tier One program that took place on September 29, 2004. It was the first competitive flight in the Ansari X PRIZE competition to demonstrate a non-governmental reusable crewed spacecraft, and is hence also referred to as the X1 flight. A serious roll excursion occurred during boost, so the flight did not achieve the expected altitude. However, it exceeded 100 km altitude, making it a successful X PRIZE flight.
Flight 17P of SpaceShipOne was a spaceflight in the Tier One program that took place on October 4, 2004. It was the second competitive flight in the Ansari X Prize competition to demonstrate a non-governmental reusable crewed spacecraft, and is hence also referred to as the X2 flight. It was a successful flight, winning the X PRIZE.
Virgin Galactic is a spaceflight company founded by Richard Branson and the Virgin Group conglomerate which retains an 11.9% stake through Virgin Investments Limited. It is headquartered in California, and operates from New Mexico. The company is developing commercial spacecraft and aims to provide suborbital spaceflights to space tourists. Virgin Galactic's suborbital spacecraft are air launched from beneath a carrier airplane known as White Knight Two. Virgin Galactic‘s maiden spaceflight occurred in 2018 with its VSS Unity spaceship. Branson had originally hoped to see a maiden spaceflight by 2010, but the date was delayed for several years, primarily due to the October 2014 crash of VSS Enterprise.
The Scaled Composites Model 339 SpaceShipTwo (SS2) is an air-launched suborbital spaceplane type designed for space tourism. It is manufactured by The Spaceship Company, a California-based company owned by Virgin Galactic.
The Boeing X-51 Waverider is an unmanned research scramjet experimental aircraft for hypersonic flight at Mach 5 and an altitude of 70,000 feet (21,000 m). The aircraft was designated X-51 in 2005. It completed its first powered hypersonic flight on 26 May 2010. After two unsuccessful test flights, the X-51 completed a flight of over six minutes and reached speeds of over Mach 5 for 210 seconds on 1 May 2013 for the longest duration powered hypersonic flight.
SpaceX CRS-1, also known as SpX-1, was SpaceX's first operational cargo mission to the International Space Station, under their Commercial Resupply Services (CRS-1) contract with NASA. It was the third flight for the uncrewed Dragon cargo spacecraft, and the fourth overall flight for the company's two-stage Falcon 9 launch vehicle. The launch occurred on 8 October 2012 at 00:34:07 UTC.
VP-03 was a sub-orbital spaceflight of the SpaceShipTwo-class VSS Unity which took place on 13 December 2018, piloted by Mark P. Stucky and co-piloted by Frederick W. "CJ" Sturckow.
VF-01 was a sub-orbital spaceflight of the SpaceShipTwo-class VSS Unity that took place on 22 February 2019, piloted by David Mackay and co-piloted by Mike Masucci. It was operated by Virgin Galactic, a private company led by Richard Branson that intends to conduct space tourism flights in the future. Following VSS Unity VP-03, VF-01 was a demonstration of the craft's ability to carry passengers. Virgin Galactic's chief astronaut trainer Beth Moses acted as a test passenger, evaluating the experience for potential customers.
The North American X-15's Flight 188 on October 3, 1967, was a record-setting flight. William J. Knight took the X-15A-2 hypersonic rocket-powered aircraft to 102,100 feet over Mud Lake, Nevada when flight 188 reached a record-setting top speed of 4,520 mph (7,270 km/h), Mach 6.70.
