Aviation historian David Myhra has been investigating secret German aircraft projects for more than 20 years, and has uncovered evidence of a diabolical Nazi plan to deliver a radioactive bomb to New York.

Through vivid 3D animation, photos, and recreations, these unusual projects are finally revealed!
