The Boeing YC-14 was a twin-engine (STOL) tactical. It was Boeing’s entrant into the United States Air Force’s Advanced Medium STOL Transport (AMST) competition, which aimed to replace the Lockheed C-130 Hercules as the USAF’s standard STOL tactical transport. Although both the YC-14 and the competing McDonnell Douglas YC-15 were successful, neither aircraft entered production. The AMST project was ended in 1979 and replaced by the C-X program.
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.
Special thanks to Scott Mahew for bringing these great pictures to my attention. These are very rare pictures of a McDonnell Douglas YC-15 being refueled by a KC-135 Stratotanker. The YC-15 was McDonnell Douglas‘ entrant into the U.S. Air Force‘s Advanced Medium STOL Transport (AMST) competition, to replace the C-130 Hercules as the USAF’s standard STOL tactical transport. In the end neither the YC-15 norBoeing YC-14 was ordered into production, although the YC-15’s basic design would be used to form the successful C-17 Globemaster III.
This F-105D Thunderchief has both a probe for probe and drogue refueling and a receptacle for boom refueling.
I’ve been searching high and low for pictures of F-104 Starfighters doing in flight refueling. I’ve finally run across some decent examples.http://www.flickr.com/photos/divemasterking2000/271653150/ http://www.flickr.com/photos/james_orear/3369142600/sizes/z/ http://www.flickr.com/photos/james_orear/3367992874/ http://www.916-starfighter.de/Gallery/gallery_sp_22.htm http://www.landspeed.com/classroom/classstarfighterhistory.html http://www.militaryfactory.com http://elpoderdelasgalaxias.wordpress.com/2012/12/09/lockheed-f-104c-starfighter-the-always-thirsty-missile-2/
A common question that I receive is what happens if there is a spark during Air Refueling; will we blow up? I think this video dramatically puts to rest any notion that there is a risk of explosion if there is a spark. The two aircraft in this video are a KC-135 and an E-4B. As the two aircraft fly through the air they pick up electrical charge at different rates. This difference is equalized by the spark that jumps between the two aircraft. It is difficult to tell from the video, but it looks like these sparks are 3-5 feet long and jumping between the tanker’s nozzle and the receiver. The dielectric breakdown of air is approximately 3 million volts per meter which suggests that there is something like 3-6 million volts difference between the aircraft.
