In the 70 years since the fall of the Third Reich, there has been much theorizing and questioning to find out just how the German military became as strong as it did so quickly.

Some of those theories venture into an area bordering on absurd. Absurd or not, however, they are possibly some of the more interesting conspiracy theories of their time.

10 1936 Black Forest Incident

According to various reports that surfaced toward the end of the 20th century, a UFO crash-landed in Germany's the Black Forest near Frieberg in 1936. It is claimed that the craft was saucer-shaped and was ultimately recovered by SS troops shortly afterward.

The object was allegedly taken to Wewelsburg Castle, the main headquarters of the Third Reich, where their top scientists worked to reverse engineer it and find ways to use the technology to their advantage. Whether they achieved this or not is open to debate, but it is widely accepted that German scientists and engineers were far ahead of other countries at the time.

Although it should be treated with a large pinch of salt, an article that appeared online in 2013 claimed that the author had been able to "channel" into the crash site that evening. He had achieved this by allegedly tracking down a pair of field glasses that had belonged to an SS officer who had witnessed the crash.

The author stated that not only were there survivors but that they were shot on sight by the SS. The article also claimed that the craft was not an alien vehicle but was, in fact, a time machine containing humans from the future.
