Depending on whether there are any ANRB Users in the areas, will RadarBox show the Shuttle Aircraft Carrier (SCA) NASA911 when it makes it's way back to the Kennedy Space Centre in Florida hopefully on Thursday morning? It's now currently at Fort Worth where it will stay overnight. If not, then I'll use the Flightaware Live Flight Tracker.

I don't think the SCA will show up on Mode S, whether or not there are RadarBox users in the area.
