FIELD: aircraft engineering.

SUBSTANCE: aircraft comprises fuselage, nose horizontal empennage, tail horizontal empennage and takeoff-landing wings suspended to fuselage by suspension units with their axes located above fuselage centerline along its lengthwise axis of symmetry to turn said takeoff-landing wings. Retracted takeoff-landing wings are located under suspension units along fuselage lengthwise axis of symmetry. Outer surface of said wings makes extension of fuselage outer surface.
