Just a heads up, the same plane might have two ADS transmitters where a callsign is only assigned to the first one hence why it may appear to be two planes.
Most of you planefags don't even know what ADS-B is, how it works, how it is not the same as radar, what it means for a plane to be BLOCKED, what it means for a plane to say No Callsign, why planes will just disappear, etc. Then you come on here and fill up an entire thread with BS just because you think you are suddenly an authority on aircraft. Can we please get back to useful discussion related to Q?
