Looking back at a few 'live sightings', I think we can now rule a few of them out. One Tweeter claimed that the race landed at Doha from Nepal, but that doesn't make sense at all. Another claimed that he saw the BB team on a flight from Doha to Beijing, which also doesn't match up with Azerbaijan. Baku doesn't connect with Doha so there'd be no reason to go there.
In fact, looking at both Tweeter's profiles, they both Tweeted an absolutely obscene amount of times on the 14th December before their 'sightings'. Almost definitely fake, and working together.
