There are already many passenger helicopters on the market, all of which are capable of vertical takeoff and landing (VTOL).
Probably any helicopter or VTOL (Vertical Take-Off and Landing) aircraft. http://en.wikipedia.org/wiki/VTOL
Reverse thrust- similar in a sense to similar use on ships and rr equipment, is used for braking purposes and backing up=on the ground. no conventional aircraft (Blimps helicopters and some stol-like things and VTOL excepted) can fly backward.
The Bell-Boeing V-22 Osprey, Harrier, F-35, anything with VTOL.
A. W. R. Gilchrist has written: 'Operating economics of VTOL and STOL transport aircraft'
known by initials VTOL which is vertical take off and landing example a Harrier jump jet
Yes, but so far mainly in the military. The most famous is the US Marines V-22 Osprey.
H. M. Dathe has written: 'Review of hovering control requirements for VTOL aircraft by a flight dynamics analysis'
Although rare, accidents have a very high chance of fatalities, and planes require a runway (exculding VTOL aircraft) as well as AIRLINE FOOD!
VSTOL = Vertical or Short Take Off and Landing aircraft. Whereas a STOL aircraft is a Short Take Off and Landing Aircraft. Maybe there is a term VTOL just for Vertical Take Off and Landing.
Vertical takeoff and landing (VTOL), usually the domain of helicopters, can also be achieved by the Harrier Jump Jet, and the Osprey tilt-rotor aircraft.
Hover VTOL (Vertical Take Off and Landing) aircraft can hover as well as helicopters, but helicopters can do it more efficiently and, therefore, can do it for longer periods.
There is a variant that does have VTOL. It will mainly be used for carrier operations
