Takeoff is the phase of flight in which an aerospace vehicle goes from the ground to flying in the air.
For horizontal takeoff aircraft this usually involves starting with a transition from moving along the ground (taxiing) 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.
For light aircraft, usually full power is used during takeoff. Large transport category (airliner) aircraft may use a reduced power for takeoff, where less than full power is applied in order to prolong engine life, reduce maintenance costs and reduce noise emissions. In some emergency cases, the power used can then be increased to increase the aircraft's performance. Before takeoff, the engines, particularly piston engines, are routinely run up at high power to check for engine-related problems. The aircraft is permitted to accelerate to rotation speed (often referred to as Vr). The term rotation is used because the aircraft pivots around the axis of its main landing gear while still on the ground, usually because of manipulation of the flight controls to make this change in aircraft attitude.
Travel is the movement of people or objects (such as airplanes, boats, trains and other conveyances) between relatively distant geographical locations.
The term "travel" originates from the Old French word travail. The term also covers all the activities performed during a travel (movement). A person who travels is spelled "traveler" in the United States, and "traveller" in the United Kingdom.[citation needed]
"The World is a book, and those who do not travel read only a page."
Reasons for traveling include recreation,tourism or vacationing,research travel for the gathering of information, for holiday to visit people, volunteer travel for charity, migration to begin life somewhere else, religious pilgrimages and mission trips, business travel,trade,commuting, and other reasons, such as to obtain health care or fleeing war or for the enjoyment of traveling. Travel may occur by human-powered transport such as walking or bicycling, or with vehicles, such as public transport, automobiles, trains and airplanes.
