This is a server replay from a random realistic battle i played few days ago, observing the battle from the viewpoint of one of the three BV-238 flying boat bombers which participated in this battle.

The music is Bach's famous BWV 565 played by one and only Karl Richter.

P.S. I do not know who are the pilots of these flying boats - and who are the fighters who were escorting them - but what they did, which i discovered checking this server replay out of curiousity - was indeed something very beautiful.
