V/STOL

V/STOL is an acronym for Vertical/Short Take-Off and Landing. V/STOL aircraft can take-off or land vertically or on short runways. The Hawker Siddeley Harrier is perhaps the most famous production V/STOL airplane.

V/STOL has been replaced by STOVL in popularity because it reduces the amount of energy required to lift a fully laden aircraft from the ground.
