I scoured the article to find out how they refuelled - the details were buried towards the end. Wow, what a way to transfer supplies and refuel 'on the wing' with a truck speeding along on the ground. A feat in itself. To to do this around 130 times without a major incident is remarkable.

EDIT: I'm also disappointed in lack of photos of the aviators and the aircraft. I am hoping the plane is still preserved somewhere and there are recent photos of it.
