Darpa999 is correct that this is unusual. Generally the tracking quits at the edge of the military restricted airspace or a bit beyond, which I
presume is done with a software "filter." This track went very close to Groom. I'm guessing they landed towards the south. That is the plane, for
lack of a better description, made a U-turn then landed. The track shown is far off the runway.
The filtering could also be done by squawk code. If you listen to Janet radio traffic, the planes maintain the Janet callsign until they switch from
Nellis control to Groom approach. At that point, the plane drops Janet and goes to the callsign of the month. The number associated with the plane
changes too. Anyway if the filtering is done by squawk code, then the plane forgot to change the squawk.
Aircraft landing at Groom use a squawk code of the format 33x, where X is a digit.
Aircraft landing at the TTR maintain the Janet callsign.
