Red Bull Stratos
Red Bull Stratos was a high altitude skydiving project involving Austrian skydiver Felix Baumgartner. On 14 October 2012, Baumgartner flew approximately into the stratosphere over New Mexico, United States, in a Gas balloon, helium balloon before free falling in a pressure suit and then parachuting to Earth. The total jump, from leaving the capsule to landing on the ground, lasted approximately ten minutes. While the free fall was initially expected to last between five and six minutes, Baumgartner deployed his parachute after 4 minutes and 19 seconds. Reaching —Baumgartner broke the sound barrier on his descent, becoming the first human to do so without any form of engine power. Measurements show Baumgartner also broke two other Flight altitude record, world records. With a final altitude of , Baumgartner broke the unofficial record for the highest manned balloon flight of previously set by Nick Piantanida. He also broke the record for the highest altitude jump, set in 1960 b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roswell International Air Center
Roswell Air Center (Roswell International Air Center; Roswell Industrial Air Center) is an airport south of Roswell, New Mexico, Roswell, in Chaves County, New Mexico, United States. History The airport was Roswell Army Airfield during World War II, and Walker Air Force Base during the Cold War. When it closed it was the largest base of the United States Air Force Strategic Air Command. Roswell Industrial Air Center was developed after the closure of Walker Air Force Base on June 30, 1967. Commercial airline flights were moved from the old Municipal airport to the Air Center shortly afterwards and Trans-Texas Airlines upgraded some of its flights serving Roswell to Douglas DC-9 jets. Walker AFB was named after General Kenneth Newton Walker, a native of Los Cerrillos, New Mexico, Los Cerrillos. He was killed during a bombing mission over Rabaul, New Britain, Papua New Guinea. on January 5, 1943. Though intercepted by enemy fighters, his group scored direct hits on nine Japanese ...

Colonel (United States)
The colonel () in the United States Army, Marine Corps, Air Force and Space Force, is the most senior field-grade military officer rank, immediately above the rank of lieutenant colonel and just below the rank of brigadier general. Colonel is equivalent to the naval rank of captain in the other uniformed services. By law, an officer previously required at least 22 years of cumulative service and a minimum of three years as a lieutenant colonel before being promoted to colonel. With the signing of the National Defense Authorization Act of 2019 (NDAA 2019), military services now have the authorization to directly commission new officers up to the rank of colonel. The pay grade for colonel is O-6. When worn alone, the insignia of rank seen at right is worn centered on headgear and fatigue uniforms. When worn in pairs, the insignia is worn on the officer's left side while a mirror-image reverse version is worn on the right side, such that both of the eagles' heads face forwa ...

Bell X-1
The Bell X-1 (Bell Model 44) 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 in 1948. A derivative of this same design, the Bell X-1A, having greater fuel capacity and hence longer rocket burning time, exceeded in 1954. The X-1 aircraft #46-062, nicknamed ''Glamorous Glennis'' and piloted by Chuck Yeager, was the first manned 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 (and non-rocket planes) designed for testing new technologies. Design and development Parallel development In 1942, the United Kingdom's Ministry of Aviation began a top secret project with Miles Aircraft to develop the world's first aircraft capable of brea ...

Chuck Yeager
Brigadier General Charles Elwood Yeager ( , February 13, 1923December 7, 2020) was a United States Air Force officer, flying ace, and record-setting test pilot who in October 1947 became the first pilot in history confirmed to have exceeded the speed of sound in level flight. Yeager was raised in Hamlin, West Virginia. His career began in World War II as a private in the United States Army, assigned to the Army Air Forces in 1941. After serving as an aircraft mechanic, in September 1942, he entered enlisted pilot training and upon graduation was promoted to the rank of flight officer (the World War II Army Air Force version of the Army's warrant officer), later achieving most of his aerial victories as a P-51 Mustang fighter pilot on the Western Front, where he was credited with shooting down 11.5 enemy aircraft (the half credit is from a second pilot assisting him in a single shootdown). On October 12, 1944, he attained "ace in a day" status, shooting down five enemy aircr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountain Daylight Time
The Mountain Time Zone of North America keeps time by subtracting seven hours from Coordinated Universal Time (UTC) when standard time ( UTC−07:00) is in effect, and by subtracting six hours during daylight saving time ( UTC−06:00). The clock time in this zone is based on the mean solar time at the 105th meridian west of the Greenwich Observatory. In the United States, the exact specification for the location of time zones and the dividing lines between zones is set forth in the Code of Federal Regulations at 49 CFR 71. In the United States and Canada, this time zone is generically called Mountain Time (MT). Specifically, it is Mountain Standard Time (MST) when observing standard time, and Mountain Daylight Time (MDT) when observing daylight saving time. The term refers to the Rocky Mountains, which range from British Columbia to New Mexico. In Mexico, this time zone is known as the or ("Pacific Zone"). In the US and Canada, the Mountain Time Zone is to the east of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phys
Physics is the natural science that studies matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. "Physical science is that department of knowledge which relates to the order of nature, or, in other words, to the regular succession of events." Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves. "Physics is one of the most fundamental of the sciences. Scientists of all disciplines use the ideas of physics, including chemists who study the structure of molecules, paleontologists who try to reconstruct how dinosaurs walked, and climatologists who study how human activities affect the atmosphere and oceans. Physics is also the foundation of all engineering and technology. No engineer could design a flat-screen TV, an interplanetary spacecraft, or even a better mousetrap without first understanding the basic laws of physics. (. ...

Comparison International Standard Atmosphere Space Diving
Comparison or comparing is the act of evaluating two or more things by determining the relevant, comparable characteristics of each thing, and then determining which characteristics of each are similar to the other, which are different, and to what degree. Where characteristics are different, the differences may then be evaluated to determine which thing is best suited for a particular purpose. The description of similarities and differences found between the two things is also called a comparison. Comparison can take many distinct forms, varying by field: To compare things, they must have characteristics that are similar enough in relevant ways to merit comparison. If two things are too different to compare in a useful way, an attempt to compare them is colloquially referred to in English as "comparing apples and oranges." Comparison is widely used in society, in science and in the arts. General usage Comparison is a natural activity, which even animals engage in when deci ...

Freeflying
Freeflying is a skydiving discipline which began in the late 1980s, involving freefalling in various vertical orientations, as opposed to the traditional "belly-to-earth" orientation. The discipline is known to have originated when Olav Zipser began experimenting with non-traditional forms of bodyflight. Zipser founded the FreeFly Clowns as a two-person competitive team with Mike Vail in 1992, and was joined by Omar Alhegelan (1st ever FAI Freestyle World Cup & World Champion), Charles Bryan, and Stefania Martinengo in 1994. The FreeFly Clowns are also credited with opening the first school to teach freeflying, The First School of Modern SkyFlying. Freeflying broke into the limelight in 1996 when the SSI Pro Tour added freeflying as a three-person competitive discipline at the second televised event (with Skysurfing), part of ESPN's Destination Extreme series. 150 countries watched the FreeFly Clowns (Olav Zipser, Charles Bryan and Omar Alhegelan) as they took 1st place in all fo ...

Terminal Velocity
Terminal velocity is the maximum velocity (speed) attainable by an object as it falls through a fluid (air is the most common example). It occurs when the sum of the drag force (''Fd'') and the buoyancy is equal to the downward force of gravity (''FG'') acting on the object. Since the net force on the object is zero, the object has zero acceleration. In fluid dynamics an object is moving at its terminal velocity if its speed is constant due to the restraining force exerted by the fluid through which it is moving. As the speed of an object increases, so does the drag force acting on it, which also depends on the substance it is passing through (for example air or water). At some speed, the drag or force of resistance will equal the gravitational pull on the object (buoyancy is considered below). At this point the object stops accelerating and continues falling at a constant speed called the terminal velocity (also called settling velocity). An object moving downward faster than ...

Red Bull GmbH
Red Bull GmbH () is an Austrian private company known for its range of energy drinks of the same name. It is also known for its sponsorship of a range of sporting events and teams. The headquarters of Red Bull GmbH are located in Fuschl am See, Salzburg. History Austrian entrepreneur Dietrich Mateschitz and Thai businessman Chaleo Yoovidhya founded Red Bull GmbH in 1984. While working for German manufacturer Blendax (later acquired by Procter & Gamble) in 1982, Mateschitz traveled to Thailand and met Chaleo, owner of TC Pharmaceuticals. He found that the energy drink Krating Daeng, developed by Chaleo's company during the 1970s, helped to ease his jet lag. After seeing market potential in the drink, he partnered with Chaleo in bringing it to Europe. Under their agreement, the partners invested $500,000 each into founding Red Bull GmbH. In return, they would each receive a 49% stake in the company, with the remaining 2% stake going to Chaleo's son Chalerm. They also agreed th ...
