The secret Nazi plan to nuke-bomb New York (documentary: video).

In this 45-minute long science/history documentary, which looks a little like something from the first Captain America movie, the very real plan of the Germans during world war two to drop a nuke on New York is explored.

How near was the scheme to becoming a goer, and making the twists and turns of history resemble the start of The Man in the High Castle?

A little too close, perhaps.
