    I have noticed for a while that the "Janet" aircraft that fly to/from McCarran in Las Vegas to both Area 51 and the Tonopah Test Range, are no longer showing up. They do show up on Flightradar24.

    I have to conclude that whoever is feeding from the Las Vegas area is filtering for whatever reason.

    Let me rephrase the above - "some" Janet aircraft seem to be filtered. Perhaps I am missing something, like MLAT coverage, or satellite ADS-B or something?

    Nothing here is filtered. Requires coverage and transponder being on and it being a mode-s transponder.

    There's probably limited coverage near 51, or they are turning off transponder.
