Wow thats amazing!
Whilst that aircraft was shown on the map and in my list (showing full ADSB), I also had another RCH aircraft, Lockheed C-5B Galaxy (L-500), AE0573 in my list...
(its callsign did show up in the list, but now after looking in my Log, the callsign is not present??)
Anyway, looked out of the window to see a huge wake trail over my house behind a heavy aircraft which blatently wasnt showing on my radar - reached for the binoculars and there it was in all its beauty Lockheed C-5B Galaxy (L-500)!
