Tethered wing structures complex flight path

A method of operating a vertical liftoff aircraft system, the vertical liftoff aircrafts system comprising:

• a plurality of unmanned wing structures configured for collective vertical liftoff;
• a plurality of tethers respectively connected to the plurality of wing structures;
• a fuselage including a connector for mechanically connecting the plurality of tethers, wherein the plurality of wing structures is operatively interconnected to the fuselage with the plurality of tethers for lifting the fuselage, and
• a control unit adapted to periodically change a flight velocity vector and enable a non-circular flight path of the wing structures resulting in an unequal load distribution of the fuselage applied on the tethers,
• the method comprising:
• vertically disposing the plurality of wing structures;
• lifting off the plurality of wing structures in a vertical direction;
• flying the plurality of wing structures along a non-circular flight path;
• periodically changing a flight velocity vector of the non-circular flight path;
• and
• lifting airborne the fuselage.
