Where did TSgt Paul Airey march after being shot down?

The journey taken by TSgt Paul Airey after being shot down is notable for its historical significance. He marched from the Baltic Sea to Berlin. This trek is emblematic of the resilience and determination displayed by many service members who found themselves behind enemy lines during wartime. Airey’s experience sheds light on the challenges faced by those evading capture, highlighting both the physical and mental endurance required in such situations.

In this context, the other choices do not reflect the actual route taken by Airey. For instance, marching from Paris to Berlin or Vienna to Warsaw would not align with the specifics of Airey's story, and the route from Berlin to Munich does not match the historical accounts of his actions after being shot down. The correct answer encapsulates a significant part of his narrative and the broader challenges faced during wartime evasion scenarios.
