There was quite a bit of debate in other threads/forums/comment sections that this was a screen recording of a flight simulator program. Among the reasons given:
1) The statement from DJI was a condemnation of anyone trying something like this, but no acknowledgement that it happened (with their equipment)
2) The poor resolution (if shot by a MP)
3) Operator claimed to try to capture the sunset (too cloudy)
4) the apparently slow speed of the fly-by
There were others, but I can't recall what they were. Given the anti-drone hype that the media seems all too willing to publish (i.e. drones at 10,000ft that later turn out to be trash bags), I wouldn't be so quick to accept any initial stories as fact. I suppose it could be true, but I'm not naive enough to believe there aren't other factors at play that generate "fake news".
