New Boeing Patent for aerial refuelling: 2 in 1 boom-and-receptacle and probe-and-drogue systems.

The design mounts the hose and drogue in the extreme tail of the tanker, with a mechanism to attach the hose to the retracted boom when required. The boom then extends, refuels the probe-equipped receiver, then retracts and the hose is detached, allowing the boom to extend to refuel a receptacle-equipped aircraft. Pretty neat.
