Aviation includes the activities surrounding mechanical flight and the aircraft industry. Aircraft includes 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. Some of the most significant advancements in aviation technology came with the controlled gliding flying of Otto Lilienthal in 1896; then a large step in significance came with the construction of 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 which permitted a major form of transport throughout the world. (Full article...)

United Airlines Flight 93 was a scheduled U.S. domestic passenger flight from Newark International Airport, in Newark, New Jersey, to San Francisco International Airport. It was hijacked by four men as part of the September 11, 2001 attacks. Over 40 minutes into the flight the hijackers breached the cockpit, overpowered the pilots and took over control of the aircraft, diverting it toward Washington, D.C. Several passengers and crew members made telephone calls aboard the flight and learned about the attacks on the World Trade Center and the Pentagon. As a result, the passengers decided to mount an assault against the hijackers and wrest control of the aircraft.

The plane crashed in a field just outside Shanksville, Pennsylvania, about 150 miles (240 km) northwest of Washington, D.C., killing all 44 people aboard, including the hijackers. Many witnessed the impact from the ground and news agencies began reporting on the event within an hour. The plane fragmented upon impact, leaving a crater, and some debris was blown miles from the crash site. The remains of everyone on board the aircraft were later identified. Subsequent analysis of the flight recorders revealed how the actions taken by the passengers prevented the aircraft from reaching either the White House or United States Capitol. A permanent memorial is planned for construction on the crash site. The chosen design has been the source of criticism and is scheduled to be dedicated in 2011. (Full article...)

Schlieren photography (from the German word for "streaks") allows the visualization of density changes, and therefore shock waves, in fluid flow. Schlieren techniques have been used for decades in laboratory wind tunnels to visualize supersonic flow about model aircraft, but not full scale aircraft until recently. Dr. Leonard Weinstein of NASA Langley Research Center developed the first Schlieren camera, which he calls SAF (Schlieren for Aircraft in Flight), that can photograph the shock waves of a full sized aircraft in flight. He successfully took a picture which clearly shows the shock waves about a T-38 Talon aircraft on December 13, 1993 at Wallops Island, MD. The camera was then brought to the NASA Dryden Flight Research Center because of the high number of supersonic flights there.

Selected biography

Wiley Hardeman Post (November 22, 1898 – August 15, 1935) was the first pilot to fly solo around the world. Also known for his work in high altitude flying, Post helped develop one of the first pressure suits. His plywood aircraft, the Winnie Mae[1] is on display at the National Air and Space Museum's Steven F. Udvar-Hazy Center in Chantilly, VA, and his pressure suit is being prepared for display at the same location. On August 15, 1935, Post and American humorist Will Rogers were killed when Post's plane crashed on takeoff from a lagoon near Point Barrow, Alaska.

AN-225 with the Soviet Space Shuttle, Buran.

The Antonov An-225 Mriya (Антонов Ан-225 Мрія, NATO reporting name: Cossack) was a strategic airlift transport aircraft built by Antonov, and was the world's largest powered aircraft before its destruction in February 2022. Mriya (Мрія) means "dream" (inspiration) in Ukrainian.

With a maximum gross weight of 640,000 kg (1,400,000 lb), the An-225 was the world's heaviest aircraft. Although its wingspan is less than that of the Hughes H-4 "Spruce Goose", the latter never went beyond a single short low-altitude test flight, making the An-225 the largest aircraft in the world to take off more than once. Both the An-124 and An-225 are larger than the C-5 Galaxy, the largest aircraft in the U.S. inventory. The An-225 was also larger than the Airbus A380.

December 7

  • 2009 – SA Airlink Flight 8625, operated by Embraer ERJ 135 ZS-SJW, overruns the runway at George Airport, South Africa, arriving from Cape Town. The aircraft sustains substantial damage when it runs down a bank onto a road and may be declared a write-off.
  • 2005 – A man named Rigoberto Alpizar, intending on American Airlines Flight 924 in Miami, is killed in the jetway by air marshalls after he threatened to have a bomb in his backpack.

The flight covered a distance of 105 miles.
  • 1945 – New Zealand National Airways Corporation is founded with amalgamation of Union Airways, Air Travel and Cook Strait Airways.
  • 1944 – The sole Northrop JB-1A Bat, unofficially known as the "Thunderbug" due to the improvised General Electric B-1 turbojets' "peculiar squeal", a jet-propelled flying wing spanning 28 feet 4 inches (8.64 m) to carry 2,000 lb (910 kg) bombs in pods close to the engines, makes its first powered, but unmanned, flight from Santa Rosa Island, Eglin Field, Florida, launching from a pair of rails laid across the sand dunes.

Pilot had used heavy brake applications before take-off, then immediately retracted the overheated undercarriage instead of letting air stream cool it, whereupon the bi-metal brakes fused. Repaired, Flying Fortress departs for Wright Field on 11 January 1937.
