Hitler's Vengeance Weapons (2001, WWII Documentary)

From a remote German island in the Baltic Sea, the first successful launch of a rocket into the stratosphere took place in October 1942. Originally all the scientist had wanted to do was go to the moon, but instead they had created Hitler's most advanced weapon of terror. This is the story of the Nazi's last desperate bid to turn the tide of WWII by unleashing an arsenal of sinister weapons. Known as V-1, a prototype cruise missile, and V-2, the first ballistic missile, the weapons caused immense civilian casualties. Enter the world of rocket scientists, secret weapons, and the race to destroy two of Hitler's most elusive weapons.
