The Red Baron was a famous ace pilot.
Behind the scenes[edit | edit source]
In the real world, "Red Baron" was a popular nickname of Manfred von Richthofen, a German ace pilot active in World War I. Several German military aviation squadrons were named after him. Some of them are mentioned in-universe. For instance, Hermann Goering is stated as "commander of the famous von Richthofen squadron" in the novel Timewyrm: Exodus. But no connection to the Red Baron is made there.
Shapiro's comment is a reference to a running gag in the Peanuts comic strip where Snoopy would battle the Baron.
