Here are some pictures of an F-16XL refueling from a KC-135. These pictures are quite rare and it took me a very long time to track them down.

These are pictures that I have been in search of for a very long time and I think they might be the new crown jewels of my collection. I was very excited when I finally was able to get copies of them.
Here are pictures of the Bell-Boeing V-22 Osprey refueling from a KC-135 boom to drogue adapter (BDA). These pictures were taken during flight testing and as of the date of this post the V-22 is not included in the ATP-56(B) refueling manual and therefore is not allowed to be refueled.
The boom to drogue adapter replaces the fuel nozzle on the tip of the boom and is attached to a 10′ internally stiffened hose that terminates in a conical drogue. The drogue and hose are not retracted inside the boom and therefore always hang out from the end of the boom. This unusual configuration often draws the attention of other aircraft and ground controllers when KC-135s operate from civilian airfields. During use, the boom is fully extended to 20 feet so that the fuel pressure in the boom does not cause it to extend.
