In November 2dn Physicist Hans Mayer hands over the Oslo Report on German weapon installations and passes it on to the British Secret Service.
The Oslo Report is one of the most important and biggest military leaks in the history of human kind. The report was written during a business trip on to Oslo, Norway. During the trip Hans wrote the report describing the German weapon systems development currently and what were the plans in the future.
