Takeoff is the phase of flight in which an aircraft goes through a transition from moving along the ground to flying in the air, usually starting on a runway.For balloons, helicopters and some specialized fixed-wing aircraft (VTOL aircraft such as the Harrier), no runway is needed.
A Royal Australian Air Force aircraftswoman demonstrating the use of an oxygen mask during a pre-flight safety demonstration on board an Australian Airbus A330 MRTT. A pre-flight safety briefing (also known as a pre-flight demonstration, in-flight safety briefing, in-flight safety demonstration, safety instructions, or simply the safety video) is a detailed explanation given before take-off to ...
An F/A-18 taking off from an aircraft carrier An Embraer E175 taking off. Takeoff is the phase of flight in which an aerospace vehicle leaves the ground and becomes airborne. For aircraft traveling vertically, this is known as liftoff.
Second security camera video; impact is at 0:25. The Department of Defense released filmed footage on May 16, 2006, that was recorded by a security camera of American Airlines Flight 77 crashing into the Pentagon, with a plane visible in one frame, as a "thin white blur" and an explosion following.

The X-14 project provided a great deal of data on VTOL (Vertical Take-Off and Landing) type aircraft and flight control systems. In 1971 , the X-14A was fitted with new engines (General Electric J85-GE-19) and redesignated the X-14B .
Aircraft flight mechanics are relevant to fixed wing (gliders, aeroplanes) and rotary wing (helicopters) aircraft. An aeroplane ( airplane in US usage), is defined in ICAO Document 9110 as, "a power-driven heavier than air aircraft, deriving its lift chiefly from aerodynamic reactions on surface which remain fixed under given conditions of flight".
