I didn't forget any aircraft,,,,,,,,there are almost 20 or 30 more, both Naval and USAF that needed to be refueled, I didn't intend to type out a complete list. (I would have had to describe the two unique ways the Banshee and Skyray received fuel, and then included the F-5A, etc)
And that first article is wrong when it talks about that Tri-level being the "first in history". (if they had said "first in USAF history" or "first time in Vietnam conflict" they might be correct)
There are quite a few photos in print of USN tri-level refuellings,,,one is Skyhawk to Skyhawk to Demon, one starts with a Skyraider, another starts with a Savage,,,,,,,,there are even a few "four-level" pics out there. They all pre-date the start of Vietnam,,,,,,and in some cases, the aircraft are still designated by the pre-DoD combined system.
Side note, I left the Savage out of the list of tankers, because of the expense or difficulty of the available kits,,,,,,,,one kit is expensive resin, another is difficult to fit plastic, another is a really great Vacuform,,,,,,,and another is a reallllly bad Vacuform. The Savage was turned into a tanker after the jet engine was removed from the tail, turning it into a two engine prop plane.
