A vertical take-off and landing (VTOL) aircraft comprising a pair of coaxial contra-rotating main lift fans 2 close to aircraft’s centre of gravity. The aircraft comprises one fan 5 on the vertical tailplane 11 for yaw control, one fan 7a, 7b on each outer wing for roll control, two auxiliary fans 4a, 4b on the horizontal tail and an optional additional nose fan for pitch control. Yaw control may be provided through differential power to main lift counter rotating fans. Separate thrusting engines 12a, 12b may be provided for forward flight. The fans may be closed with fan bay doors for forward flight. Preferably, upper and lower beams 1, 3 provide for mounting main fans, structural continuity in the fore-aft direction, attachment of landing gear and vertical tailplane. Main lift proportion may be generated within the fuselage width. Front and rear spars 8, 6 may form fan duct outer edge.
