An Embraer E-175 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. For aircraft that take off horizontally, this usually involves starting with a transition from moving along the ground on a runway.
The Lockheed SR-71 Blackbird holds the official Air Speed Record for a crewed airbreathing jet engine aircraft with a speed of 3,530 km/h (2,190 mph). The record was set on 28 July 1976 by Eldon W. Joersz and George T. Morgan Jr. near Beale Air Force Base, California, USA. It was able to take off and land unassisted on conventional runways. [47]
On a typical mission, the SR-71 took off with only a partial fuel load to reduce stress on the brakes and tires during takeoff and also ensure it could successfully take off should one engine fail. [88] Within 20 seconds the aircraft traveled 4,500 feet (1,400 m), reached 240 miles per hour (390 km/h), and lifted off.
Boeing C-32. The Boeing 757 is an American narrow-body airliner designed and built by Boeing Commercial Airplanes. The then-named 7N7, a twinjet successor for the trijet 727, received its first orders in August 1978. The prototype completed its maiden flight on February 19, 1982, and it was FAA certified on December 21, 1982.
The Boeing 747 is a long-range wide-body airliner designed and manufactured by Boeing Commercial Airplanes in the United States between 1968 and 2023. After the introduction of the 707 in October 1958, Pan Am wanted a jet 2+1⁄2 times its size, to reduce its seat cost by 30%. In 1965, Joe Sutter left the 737 development program to design the 747.
Takeoff is the phase of flight in which an aircraft goes through a transition from moving along the ground (taxiing) 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. Takeoff is the opposite of landing.
During the late 1990s, Boeing considered replacement aircraft programs due to slowing sales of the 767 and 747-400.Two new aircraft were proposed. The 747X would have lengthened the 747-400 and improved efficiency, and the Sonic Cruiser would have achieved 15% higher speeds (approximately Mach 0.98) while burning fuel at the same rate as the 767.

Gulfstream G550. The Gulfstream V (Model GV, pronounced "G-five") is a long-range, large business jet aircraft produced by Gulfstream Aerospace, derived from the previous Gulfstream IV. It flies up to Mach 0.885 (508 kn; 940 km/h), up to 51,000 feet (16,000 m) and has a 6,500 nmi (12,000 km) range. It typically accommodates four crew and 14 ...
