This is the WWI memoirs of Medal of Honor winner, Capt Eddie Rickenbacker. He fought in and eventually became commander of the 94th "Hat-in-the-Ring" Squadron, which ended the war with the highest number of air victories of any American squadron. The circus mentioned in the title refers to the German squadron commanded by the famous Red Baron, Manfred von Richthofen.
As a producer of audio books relating to WWI I was really interested in listening to this free offering from Librivox. I was not disappointed. As the description says its the memoirs of Captain Rickenbacker and it starts out with him joining up and having to fly hand-me-down aircraft that are really quite pitiful. These aircraft were not only slower and less manoeuvrable that the German aircraft they had a tendency for the wing covering to peel off in flight!
It's quite a fascinating listen. Rickenbacker is not a natural pilot ace, as you follow his story you'll hear him working on his tactics trying to work out how to defeat the enemy. he has to keep learning as his squadron keeps getting new missions. They attack enemy fighters, then bombers, strafe the ground and even take on observation balloons.
Later they get better planes and the tables are turned, and they even come up against the famous ace pilots of Flying Circus mentioned in the title.
If you have interest in WWI, then this is a natural for you to download, and I reccomend that you do.
