United States Air Force F-15C Eagles flying in a Vic formation over Alaska. Formation flying is the flight of multiple objects in coordination. Formation flying occurs in nature among flying and gliding animals, and is also conducted in human aviation, often in military aviation and air shows.
Studies on theropod dinosaurs do suggest multiple (at least 3) independent acquisitions of powered flight however, [1] [2] and a recent study proposes independent acquisitions amidst the different bat clades as well. [3] Powered flight uses muscles to generate aerodynamic force, which allows the animal to produce lift and thrust. The animal may ...
Lesser flamingos flying in formation. When in gliding flight, the upward aerodynamic force is equal to the weight.In gliding flight, no propulsion is used; the energy to counteract the energy loss due to aerodynamic drag is either taken from the potential energy of the bird, resulting in a descending flight, or is replaced by rising air currents ("thermals"), referred to as soaring flight.
Flight tracking data from the moments before the fatal midair collision on Wednesday appear to show the Black Hawk helicopter flying above the maximum allowed altitude at times and veering off the ...
The collision was captured by a webcam at the John F. Kennedy Center for the Performing Arts, [36] [37] and another video showed a brief trail of fire. [38] Other videos showed that the collision may have damaged the rotor blades of the Blackhawk and the left wing of the CRJ700 as the airliner fell in a left-hand spiral into the water. [39]
How do photos from the 1972 Andes plane crash that inspired "Society ... which happened in October 1972 when Uruguayan Air Force Flight 571 crashed into the Andes mountains, immediately killing 12 ...
Supersonic flight is associated with the formation of shock waves that form a sonic boom that can be heard from the ground, [10] and is frequently startling. The creation of this shockwave requires a significant amount of energy; because of this, supersonic flight is generally less efficient than subsonic flight at about 85% of the speed of sound.
Investigators head into the debris field at the site of a commercial plane crash near Shanksville, Pennsylvania, September 11, 2001. The crash is one of four planes that were hijacked as part of a ...
