I am assuming that was a regularly scheduled flight so lets look at the radar tracks from the previous days (weeks) and compare that to what we see here.
... that’s a privately-run website, not some “official source”.
I am amused by your faith in official source(s).
My point is not that “official sources” are reliable, but that a site like FlightRadar, which is solely for entertainment, should not be given the kind of credibility it’s being given in that video. It’s not an authoritative source. Those sites do not get feeds from ATC, except over the US and then its on a 5-minute delay. The name “FlightRadar” is misleading, since it does not rely on radar in the first place.
