Never fails to keep me interested searching this App. Just been tracking Singapore 319 a B777 at Lv310 heading en route Singapore from LHR AT 22.20 passing Rostov-on-Don. Then I noticed a second aircraft in trail same callsign SIA319 and reg. only variation was the map ref Long and Lat of both aircraft was different and the airspeed had a small variation of about 10 kts. after several moments tracking them the second aircraft details vanished.
