Unmanned aircraft drone refuels autonomously in MID-AIR for longer missions

It is one of the trickiest inflight manoeuvres performed by military fighter pilots, but now drones have shown they too can refuel in mid-air. Engineers in China have developed a way for drones to be able to carry out autonomous aerial refuelling (AAR). It could enable unmanned aircraft to carry out longer missions over greater distances without having to return to base for refueling. Engineers have developed drones that can refuel in midair.
