Aviation includes the activities surrounding mechanical flight and the aircraft industry. Aircraft include fixed-wing and rotary-wing types, morphable wings, wing-less lifting bodies, as well as lighter-than-air aircraft such as hot air balloons and airships.

Aviation began in the 18th century with the development of the hot air balloon, an apparatus capable of atmospheric displacement through buoyancy. Clément Ader built the "Ader Éole" in France and made an uncontrolled, powered hop in 1890. This was the first powered aircraft, although it did not achieve controlled flight. Some of the most significant advancements in aviation technology came with the controlled gliding flying of Otto Lilienthal in 1896. A major leap followed with the construction of the Wright Flyer, the first powered airplane by the Wright brothers in the early 1900s.

Since that time, aviation has been technologically revolutionized by the introduction of the jet engine which enabled aviation to become a major form of transport throughout the world. In 2024, there were 9.5 billion passengers worldwide according to the ICAO. As of 2018, estimates suggest that 11% of the world's population traveled by air, with up to 4% taking international flights. (Full article...)

Aerodynamics is a branch of dynamics concerned with studying the motion of air, particularly when it interacts with a moving object. Understanding the motion of air (often called a flow field) around an object enables the calculation of forces and moments acting on the object. Typical properties calculated for a flow field include velocity, pressure, density and temperature as a function of position and time. By defining a control volume around the flow field, equations for the conservation of mass, momentum, and energy can be defined and used to solve for the properties. The use of aerodynamics through mathematical analysis, empirical approximation and wind tunnel experimentation form the scientific basis for heavier-than-air flight.

External aerodynamics is the study of flow around solid objects of various shapes. Evaluating the lift and drag on an airplane, the shock waves that form in front of the nose of a rocket is an example of external aerodynamics. Internal aerodynamics is the study of flow through passages in solid objects. For instance, internal aerodynamics encompasses the study of the airflow through a jet engine.

The ratio of the problem's characteristic flow speed to the speed of sound comprises a second classification of aerodynamic problems. A problem is called subsonic if all the speeds in the problem are less than the speed of sound, transonic if speeds both below and above the speed of sound are present (normally when the characteristic speed is approximately the speed of sound), supersonic when the characteristic flow speed is greater than the speed of sound, and hypersonic when the flow speed is much greater than the speed of sound. Aerodynamicists disagree over the precise definition of hypersonic flow; minimum Mach numbers for hypersonic flow range from 3 to 12. Most aerodynamicists use numbers between 5 and 8.

The controlled impact demonstration
The controlled impact demonstration
On December 1, 1984, NASA and the Federal Aviation Administration (FAA) conducted the Controlled Impact Demonstration, where they deliberately crashed a Boeing 720 aircraft with the intent of improving occupant crash survivability. Seen left-to-right, top-to-bottom, the plane makes a practice approach, hits the ground, slides for a short distance, strikes posts cemented in the ground, and becomes engulfed in flames.

Selected biography

Charles Yeager
Charles Elwood "Chuck" Yeager (born February 13, 1923) is a retired Brigadier-General in the United States Air Force and a noted test pilot. In 1947, he, at age 24, became the first pilot to travel faster than sound in level flight and ascent.

His career began in World War II as a private in the U.S. Army Air Forces. 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 (WW 2 U.S. Army Air Forces rank equivalent to Warrant Officer) and became a P-51 Mustang fighter pilot. After the war he became a test pilot of many kinds of aircraft and rocket planes. Yeager was the first man to break the sound barrier on October 14, 1947, flying the experimental Bell X-1 at Mach 1 at an altitude of 45,000 ft (13,700 m). Although Scott Crossfield was the first man to fly faster than Mach 2 in 1953, Yeager shortly thereafter exceeded Mach 2.4. He later commanded fighter squadrons and wings in Germany and in Southeast Asia during the Vietnam War, and in recognition of the outstanding performance ratings of those units he then was promoted to Brigadier-General. Yeager's flying career spans more than sixty years and has taken him to every corner of the globe, even into the Soviet Union during the height of the Cold War.

October 19

  • 1992 – A Panavia Tornado crashes in the evening on the Nellis AFB, Nevada range, 100 miles NE of Las Vegas, during Red Flag combat exercises, killing two crew from the Italian Air Force.
  • 1988 – Indian Airlines Flight 113, a Boeing 737, hits an electric mast 5 miles (8 kilometers) out on approach in poor visibility in Ahmedabad, India. All six crew members and 124 of 129 passengers are killed.
  • 1986 – República de Moçambique Tupolev Tu-134A-3, C9-CAA, c/n 63457, with crew of nine and 35 passengers, crashes on approach at 2121 hrs. to Maputo International Airport (MPM/FQMA), Mozambique after flight from Mbala Airport (MMQ), Zambia, killing eight crew and 26 passengers, including Mozambique President Samora Machel who had attended a meeting of African leaders in Zambia. While approaching Maputo, an inadvertent selection of the MATSAPA VOR frequency caused the crew to execute a premature 37-degrees turn. Although the pilot queried the turn, no effort was made to verify it by using the available navigational aids. The aircraft descended below the 3000 feet limit in spite of not having visual contact with Maputo. The crew erroneously assumed a power failure at Maputo. A 32-second GPWS warning was ignored and the aircraft collided with the ground at 2187 feet, bounced and crashed into an uphill slope. The aircraft broke up, slid across the South African/Swaziland border and caught fire.
  • 1978 – A USAF Boeing B-52D-75-BO Stratofortress, 56-0594, of the 22d Bomb Wing, crashes at 0730 hrs. in light fog in a plowed field ~2.5 miles SE of March AFB, near the rural community of Sunnymead, California, shortly after take-off. Five crew killed, but one is able to escape the burning wreckage and was reported in stable condition at the base hospital. Traffic was disrupted on nearby Interstate 15E.
