Helicopters obviously have limited load-lifting capability.
Today’s invention is a frame (red) to which individual helicopters can be bolted in order to allow truly massive weights to be transported easily, with the load shared between n rotary-wing aircraft.
Given that no pilot is keen to have their craft attached to others, the frame would also contain circuitry which allows n-1 uncrewed machines to be controlled in synchrony from a master helicopter.
