Been here on and off all day. What's up? If it's about Yahoo70 on ADS-B, it's a drone.
Clean up in Aisles 4, 10 and 20
ADS-B shows the track as Friedrichshafen Airport, at the bottom of the Black Forest area.
Something is wrong with these altitudes, -1000 and over 50,000ft????
Must have been a gitch in ADS-B. RCH505 is now at angels 30 headed West. RCH498 headed NW at angels 50.
