To solve a problem wherein a technology of a practically viable vertical takeoff and landing airplane is required, the airplane securing horizontal flight performance and a cruising distance substantially equal to a general airplane, having vertical takeoff and landing performance equal to a helicopter without requiring a wide runway, and not requiring complicated aerodynamic calculation with a simple structure.

For solving the problem, this airplane is equipped as follows : (1) to a structure of the general airplane having a main wing, a tail and a vertical tail, the main wing is formed as two of a front main wing and a rear main wing, and a pair of left-right propelling propellers are equipped in the respective main wings, (2) the front-rear main wings are varied stepwise up to the substantially vertical from the substantially horizontal, and in takeoff and landing, the four propellers in total are set upward, and enable a vertical up-down motion such as the helicopter, (3) for preventing reduction in aerodynamic performance of the rear main wing by a turbulence by the front main wings and the propelling propellers installed on the front main wings, the propellers installed on the rear main wings are dislocated a little from a just behind position by the propellers of the front main wings, and (4) a rotary shaft is provided in a position thickest in a thickness of the main wings, and this rotary shaft connects left-right main wings by penetrating through a fuselage.
