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 ...
The basic principles of air navigation are identical to general navigation, which includes the process of planning, recording, and controlling the movement of a craft from one place to another. [ 1 ] Successful air navigation involves piloting an aircraft from place to place without getting lost, not breaking the laws applying to aircraft, or ...
Supersonic flight is flight faster than the speed of sound. 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 ...

A 2007 biography of Cayley (Richard Dee's The Man Who Discovered Flight: George Cayley and the First Airplane) claims the first pilot was Cayley's grandson George John Cayley (1826–1878). A replica of the 1853 machine was flown at the original site in Brompton Dale by Derek Piggott in 1973 [ 25 ] for TV and in the mid-1980s [ 26 ] for the ...
The principles of flight dynamics are used to model a vehicle's powered flight during launch from the Earth; a spacecraft's orbital flight; maneuvers to change orbit; translunar and interplanetary flight; launch from and landing on a celestial body, with or without an atmosphere; entry through the atmosphere of the Earth or other celestial body ...
YouTube earlier this year wound down most of its originals division, in a significant pullback on its investment in scripted and unscripted programming. But it’s not totally out of the game ...
YouTube Kids has faced criticism from advocacy groups, particularly the Fairplay Organization, for concerns surrounding the app's use of commercial advertising, as well as algorithmic suggestions of videos that may be inappropriate for the app's target audience, as the app has been associated with a controversy surrounding disturbing or violent ...
