How do you refuel a massive B-52 Stratofortress in mid-air? Carefully and very precisely as the video at the top of this article shows.
Four of the massive strategic bombers have been based at RAF Fairford in Gloucestershire since February on a pre-planned deployment that has come at the same time as Russia's invasion of Ukraine. They have flown a number of missions over Europe and their flight paths have taken them over large areas of England and Wales.
In the video above, which was filmed in October 31, 2018, a KC-135 Stratotanker refuels a B52 bomber. The KC-135 had taken off from the Andersen Air Force base in Guam, a western island in the Pacific for the B52 refuelling mission.
