Welcome to the DLR discussion forum. I hope someone local can chime in with more info on activities there. Regarding the hex codes: They are in the range assigned to TIS-B. Very generally speaking TIS-B is similar to ADS-B, but the codes are temporary and assigned at random. Without access to the logs of the assigning ATC agency it is impossible to identify an aircraft by the TIS-B code is transmits. Jets taking off from Nellis often transmit TIS-B codes until they leave civilian airspace to comply with FAA regulations. When the aircraft reaches military airspace the TIS-B transmitter is turned off and the aircraft "disappears" on the tracker. All that said, the tankers may have enabled TIS-B to assist with collision avoidance during landing. So they appeared as two different aircraft, with two different hex codes each. The fact that they "disappeared" could simply be due to poor coverage at low altitude in that area.
