The aircraft was ID'd only by the 6-digit Mode-S code. It did not transmit a call sign/registration number. I suppose operating only inside the ranges they can send whatever Mode-S code they want since they are in USAF controlled air space. But during the Sept 2020 visit they did a fairly extensive round trip east of the ranges in public air space with the wrong code. I suppose with the numbers being only one binary digit off they could always say: "oops, our bad; set the wrong code". It happens sometimes with civilian aircraft. I have a number of known mis-codes in my database.
