The present invention, in the field of aviation, is a Vertical Take-Off and Landing (VTOL) vehicle comprising fuselage, vertical tail, four tilting wings, electric generator which uses liquid fuel, rechargeable electric energy storage devices, sensors comprising air flow sensors and an actuation and feedback control system. The four tilting wings may rotate, independently one from the other and in a controlled way, around two axes parallel to the pitch axis, one of these axis is in front of the center of gravity of the vehicle and the other behind it. All the four wings provide positive lift during forward flight. There is at least one electric motor in each wing which drives at least one thrust generator. The thrust generators wind streams interact with all the vehicle lifting wings during vertical take off and landing to reduce the possibility to stall at low vehicle speed. The thrust generators may provide a combined thrust higher than the aircraft weight; the power required to drive the electric motors comes from the electric generator and the additional power required to provide a thrust higher than the aircraft weight comes from rechargeable electric energy storage devices such as batteries or supercapacitors. An active feedback system allows to control the rotational speed of each thrust generators and the tilt angles of each wing and the rudder on the basis of given flight inputs such as aircraft direction and speed.
