no back again, 3 aircraft with same altitude/squawk etc , 2 of the A319's from the same airline and the other a J41 from a different airline, the 2 airbuses mode s codes are very close but the J41 is very different. on the map it plots both airbuses in the same spot but the J41 does not plot as no ADS, all 3 timed out at the same time??
