Last week, in MLAT Aug.30,2017 RSD047 RA-64526
This flight path is not on the Coverage Map map.
The FlightAware ADS-B Coverage Map has just been updated an hour ago (UTC 5PM, by the way this is also unusual. The map was always updated on Monday at UTC 9 AM).
Now the MLAT map looks like this in different browsers.
By the way, what period of data accumulation? Sunday - Saturday?
Because I do not see the flight of an airplane with an unusual trajectory on the Coverage Map - http://flightaware.com/live/flight/RA3737G/history/20170903/1102Z
