Discovery Channel - Escape from Berlin (2002)

Escape from Berlin aka Flucht Aus Berlin

A programme on the courage and ingenuity of East Germans who were willing to risk their lives escaping through, over, and even under, the murderous Wall that divided Berlin between 1961 and 1989. The programme includes astonishing actuality footage of escapes as they happened (such as tunnelling, swimming and even escaping in a microlight aircraft) along with recreations of some of the most daring escape attempts, and some of the deadly failures.
