Planefag Report
US Marshals Service JPAT (Joint Prisoner Air Transport?) Boeing 737 descending into Las Vegas. Looks like it departed from Boeing Field in Seattle.
Just retrofitted?
MI have control of ADSBExchange, they even know what you're monitoring. Found that out during the NK incursion on 11/11/17.
I believe there are alternative ADSB concentrators/networks available as they are user operated receivers.
US Marshals Service JPAT 737 descending into Nellis AFB.
Talk about ADSB fuckery. US Marshals JPAT 737 circled around Las Vegas and, just as it should have been turning for final towards McCarran Int'l, it went to ground and is just spinning at this location, still receiving ADSB messages for at least a minute.
