Flys

Aircraft - a device for flight in the atmosphere or outer space. Aircraft are aerostatic or devices "lighter than air" that rises in atmospheric flight Archimedean force through the cylinder (shell), gas-filled, airships with engines and controls for targeted vertical movement (up or down) and horizontal, wind - the devices that are supported in atmospheric flight, aerodynamic lift, helicopters, which creates lift propeller rotated around the vertical axis of the engine, airplane with aerostatic unloading, at about 80% in which lift aircraft (500 tons) achieved by the balloon with helium, rocket - the devices, overcoming the force of gravity without any interaction with the atmosphere, due to thrust rocket engine and others.
