Then he realized that the approaching machine was simply a vertical takeoff and landing aircraft.

"I've been involved in vertical takeoff and landing all my life," Yoeli says.

"With vertical takeoffs and landings, it won't be too risky," said Joe.

The work relating to vertical takeoff and landing techniques was also invaluable.

This condition is recognizable when coming to a hover following a vertical takeoff.

It was equipped with 4 small swivelling jets for vertical takeoff and landing.

With the lever back, the nozzles point downward for vertical takeoff or landing.

Intelligence provided the latest in research from the British, the leaders in the vertical takeoff and landing aircraft.

The procedure for vertical take-off involves facing the aircraft into the wind.

All eight engines act as boosters during vertical take-off.

Facing a slight slope, the flying windmill had made an almost vertical take-off.

His work with aircraft stability led him to invent an early version of a vertical short take-off and landing airplane.

In addition to the helicopter, many approaches have been tried to develop practical aircraft with vertical take-off and landing capabilities.

The first successful unmanned vertical take-off from the experimental launch tower occurred on 22 December 1944.

It is a vertical take-off and landing quadrotor that requires minimal deployment time.
