This would be a nice place to discuss the aviation side of things.
Couple of things that caught my eye recently, this article from Michael O'Leary.
"O’Leary said Ryanair was flying humanitarian cargo in the belly of its planes “for the first time in 30 years” to Polish airports, liaising with Ukrainian embassies."
I would have thought given their network size they would have offered free flight to Ukrainians trying to reach other family across Europe but I see that Wizz Air is offering rescue flights.
Tracking the Oligarchs private jets is another good one. I saw the twitter page when it had 3000 followers. It is now up to over 240k.
Finally watching the aeroflot flights on FR24 is showing some really interesting routes to avoid european airspace.
