Buddy tank refuelling is a technique used by military pilots to extend the range of their aircraft by refuelling in mid-air. There are several synonyms for this process, including aerial refuelling, air-to-air refuelling, in-flight refuelling, and tanking. All of these terms refer to the process of transferring fuel from one aircraft to another while in flight. This technique allows aircraft to fly much longer distances without the need to land and refuel, making it a crucial tactic in military operations. Buddy tank refuelling requires highly skilled pilots and precise communication between the two aircraft involved, ensuring the safety and success of the manoeuvre.
