"Houston, we have a problem!" (Yugoslavian space program)

This documentary claims to reveal the secret yugoslav space program which fueled the technological advancements of NASA with the help of Herman Potočnik´s unpublished diaries. It presents the supposed hidden (third) side of the Space Race during the Cold War and how Marshal Josip Broz Tito negotiated lucrative deals with the United States and built the biggest underground space centre in Europe, making the Apollo missions and landing on the moon a reality.
