 FACT: In this episode Prof. Brian J. Ford states that the difference  between the Nazi "antipodal bomber" and the US space shuttle is that  the former has engines while the Shuttle does not. This is not true.  The US space shuttle has three main engines, each producing 400,000  lbs of thrust at liftoff. Neither the antipodal bomber designed by  the Nazis nor the space shuttle were designed to use their engines  during the decent and landing stages.
