I do not believe this is a man made craft, I assume it is a ancient craft, same craft which crashed in Roswell. I have been studying UFOs for over a decade and my suspicious feeling is this craft was found by Germany and fell in NATOs hand at the end of WW2.
As the secret attempt to fly the craft it was crashed in Roswell and that's how that story comes into play. As the military attempts to back engineered this crafts technology the military has been designing similar vehicles but none to its size. Note this craft is huge! Tremendous, it's bigger than 4 airliners back to back.
The TREVATRON and HADRON collider are based on the supposed energy which generates this large craft.
