The sound barrier was broken using the Bell X-1 aircraft twelve years later, thanks in part to those individuals.

The Ford X-1 was a roadster built to contest the Fall 1965 North American Pro Series, a forerunner of Can-Am, entered by the Bruce McLaren team and driven by Chris Amon.

An Aerobee 150 rocket was launched on June 12, 1962 and it detected the first X-rays from other celestial sources ( Scorpius X-1 ).

In October 1947, the Bell X-1 was the first aircraft to exceed the speed of sound.

The first plane to break the sound barrier in level flight was a rocket plane – the Bell X-1.

In November 2010 Sinclair told The Guardian newspaper that he was working on a new prototype electric vehicle called the X-1, to be launched within a year.

" The X-1 was slated to become available in July 2011 at the price of £ 595.

" He said the prototype was called the X-1.

GM developed a gasoline-electric drive hybrid the XP-833 and Pontiac the X-1 a rear wheel mid engine car that was powered by a radical X-shaped aircraft type air-cooled two-stroke radial engine where the standard crankshaft was replaced by a unit called a Scotch yoke.

Cygnus X-1 was the first X-ray source widely accepted to be a black hole candidate and it remains among the most studied astronomical objects in its class.

Cygnus X-1 was the subject of a friendly scientific wager between physicists Stephen Hawking and Kip Thorne in 1974, with Hawking betting that it was not a black hole.

Cygnus X-1 was discovered using X-ray instruments that were carried aloft by a sounding rocket launched from White Sands Missile Range in New Mexico.

With further observations strengthening the evidence, by the end of 1973 the astronomical community generally conceded that Cygnus X-1 was most likely a black hole.

This X-ray image of Cygnus X-1 was taken by a balloon-borne telescope, the High Energy Replicated Optics ( HERO ) project.

Past analysis of data from the space-based Chandra X-ray Observatory suggested that Cygnus X-1 was not rotating to any significant degree.

Also featuring the all-moving tail, the XS-1 was later known as the X-1.

It was in the X-1 that Chuck Yeager was credited with being the first man to break the sound barrier in level flight on 14 October 1947, flying at an altitude of 45, 000 ft ( 13. 7 km ).

Uhuru observed the SMC on January 1, 12, 13, 16, and 17, 1971, and detected one source located at 01149-7342, which was then designated SMC X-1.

One of the most famous high-mass X-ray binaries is Cygnus X-1, which was the first identified black hole candidate.

NACA claims credit for having the first aircraft to break the sound barrier ( although the aircraft, the Bell X-1, was controlled by the Air Force and flew with an Air Force pilot when it broke the sound barrier ).

A later Aerobee rocket launched from White Sands Missile Range on July 7, 1967, yielded further evidence that the source Virgo X-1 was the radio galaxy Messier 87.

Until this time, launch vehicles such as the Pegasus rocket, or rocket planes such as the X-1, X-15, or SpaceShipOne, which were carried under an aircraft pointing in the same direction as the fuselage, would have their engines ignited either just before being air-dropped or a few seconds afterward.

Observation of Circinus X-1 in July 2007 revealed the presence of X-ray jets normally found in black hole systems.

Cir X-1 was not detected at all during a July 5, 1975 observation, providing an upper limit on the emission of 3. 5e-11 erg · cm < sup >- 2 ·</ sup > s < sup >− 1 </ sup > ( 35 fW / m² ) in the 0. 2 to 2. 0 keV ( 32 to 320 aJ ) range.

LMC X-1 ( the first X-ray source in the LMC ) is at RA Dec, and is a high mass X-ray binary source ( HMXB ).

Of the first five luminous LMC X-ray binaries: LMC X-1, X-2, X-3, X-4, and A 0538-66 ( detected by Ariel 5 at A 0538-66 ); LMC X-2 is the only one that is a bright low-mass X-ray binary system ( LMXB ) in the LMC.

Probably the best known example of an X-ray binary at present is the high-mass X-ray binary Cygnus X-1.

Cygnus X-1 belongs to a high-mass X-ray binary system about from the Sun that includes a blue supergiant variable star designated HDE 226868 which it orbits at about 0. 2 AU, or 20 % of the distance from the Earth to the Sun.

In April – May 1971, Luc Braes and George K. Miley from Leiden Observatory, and independently Robert M. Hjellming and Campbell Wade at the National Radio Astronomy Observatory, detected radio emission from Cygnus X-1, and their accurate radio position pinpointed the X-ray source to the star AGK2 + 35 1910 = HDE 226868.

The HDE 226868 / Cygnus X-1 system shares a common motion through space with an association of massive stars named Cygnus OB3, which is located at roughly from the Sun.

This implies that HDE 226868, Cygnus X-1 and this OB association may have formed at the same time and location.

Notable occurrences at Edwards include Chuck Yeager's flight that broke the sound barrier in the Bell X-1, test flights of the North American X-15, the first landings of the Space Shuttle, and the 1986 around-the-world flight of the Rutan Voyager.

In the mid-1940s, Bell Aircraft Corporation tested its X-1 supersonic jet at Pinecastle Army Airfield, because of the area's then-remote location and runway.

XS-1 flight number 50 is the first one where the X-1 recorded supersonic flight, at Mach 1. 06 ( 361 m / s, 1, 299 km / h, 807. 2 mph ) peak speed ; however, Yeager and many other personnel believe Flight # 49 ( also with Yeager piloting ), which reached a top recorded speed of Mach 0. 997 ( 339 m / s, 1, 221 km / h ), may have, in fact, exceeded Mach 1.

The SMC X-1, a HMXRB, is at J2000 right ascension ( RA ) declination ( Dec ).

On September 30, 1946, five NACA engineers, headed by Walter C. Williams, arrived at Muroc Army Airfield ( now Edwards AFB ) from Langley Aeronautical Laboratory, VA, to prepare for X-1 supersonic research flights in joint NACA-Army Air Forces program.

This solution was used on a number of designs beginning with the Bell X-1, the first manned aircraft to fly at the speed of sound.

However, aircraft such as the Bell X-1, F-86 Sabre and Convair F2Y Sea Dart similarly did not have area ruled fuselages yet are acknowledged to have flown at supersonic speeds — here the engine thrust, either alone or in combination with the pull of gravity during a dive, supplies enough force to accelerate the airplane to supersonic speed.

The US X-1 at sea

The x-ray source at the core of NGC 300 is designated NGC 300 X-1.

Over the next five years, he flew nearly all of the experimental aircraft under test at Edwards, including the X-1, XF-92, X-4, X-5, Douglas D-558-I Skystreak and the Douglas D-558-II Skyrocket.

Beginning in January 1946, Bell Aircraft Corporation tested its X-1 supersonic aircraft, originally designated the XS-1 at the airfield, because of the area's then-remote location and 10, 000-foot runway.

A move to the remote California desert ensured the X-1 project team could maintain secrecy, an important issue considering the project was highly classified at the time.

In September 1947, the first of three XP-86 prototypes ( s / n 45-59597 ) was moved from North American ’ s Mines Field ( later Los Angeles International Airport ) to the Muroc North Base test facility ( now Edwards AFB ), the same base at which the Bell X-1 was being tested.
