Drone and separate vehicle body that are assemblable to form vehicle such as hovercraft

In one aspect, there is provided a combination vehicle system, including a drone and a hovercraft body. The drone has a plurality of motor-driven rotors and a controller. The hovercraft body defines a ground-facing chamber having a hover air inlet, and includes a mount for the drone. The drone is removably connectable to the mount in a mounted position so as to form a hovercraft. The controller is programmed to drive the plurality of rotors to maintain stable flight of the drone without the hovercraft body connected thereto. The controller is programmed to drive the first rotor to at least partially lift the hovercraft off a support surface and to drive the second rotor to propel the hovercraft along the support surface.
