A vertical take-off and landing aircraft has an upwardly-open U-shaped channel extending from a front edge to a rear edge of each of two fixed wings and a thrust providing device, such as a propeller, mounted for tilting at the rear end of the channel. The thrust providing device has an inlet at which low pressure is produced by drawing in air along a path and the thrust providing device is tilted to vary the angle of the air drawing-in path relative to the wing and effect vertical take-off and landing by variably enhancing the lift of the wing.
