Caracal Models has done a lot of us a real favor by reproducing their now sold out 1/72 KC-135R sheet in 1/144 for those of us who don't have the shelf space for the larger kit. While no kit is listed, I do believe that the only one done in this scale is by Minicraft, so locating it should not be all that difficult. 

The sheet itself is quite comprehensive and includes markings for 16 different aircraft, just like the larger scale version.  While all the wings are not covered, a lot of them are. All the planes are in the current AMC Grey scheme that has been worn for many years. Note that most if not all of them do not have the upper wingwalk areas so keep that in mind.
