Video: The history of aerial refuelling is pure nuts. Back on 12 November 1921, the first aeroplane to aeroplane refuelling happened and it required a guy, Wesley May, strapping a 19L can of petrol on his back and walking on the wing of one aeroplane and hopping over to the wing of the other aeroplane to refuel. That's crazy!
Thankfully, we've gotten a lot better at aerial refuelling and figured out better systems like using a hose, a boom system, a drogue method and the KC-10 to do all of that. Watch the video above to see how aerial refuelling worked.
