Sacred Haven of Debauchery

A squadron of fighter jets, four of them, flew over my house a minute ago, making an incredible noise. This is... unusual.

I often see fighter jets flying overhead, although they fly quite high. For example, I see them in the run-up to May 9th. As far as I know, there's a military airfield not too far away, Chkalovsky, and that's where they fly from.
