The old basket style?

Is that where some airman climbed down the drogue and filled the planes bucket by bucket?

The honey bucket crews in Korea.
Some poor slob with a pole across his shoulder with buckets tied to either side dumps the buckets in to the holding tank and passes it up to some other poor slob to dump in to the truck.
Good times.

[Ozark Tom]

Imagine a shuttlecock on the end of a fuel hose deployed from a tanker aircraft. Traditionally, smaller aircraft had a forward mounted refuel probe, which the feathers guided to a valve in the center of the drogue.
