We’re told of a NASA engineer named Joseph Blumrich. In the early 70’s he wasn’t convinced that what Ezekiel saw was a spaceship… so he went ahead and tried to re-create it. In the process he managed to convince himself that what Ezekiel saw really was a spaceship, and he wrote a book about it.
He basically interpreted the story by changing or discarding any part of the description that didn’t fit in with the spaceship hypothesis, and making a whole bunch of unwarranted assumptions. In the end he got the model of an alien ship that you see pictured on his book cover above.
A few years later, we’re told, a German structural engineer named Hans Herbert Bayer decided to make a blueprint for the temple in Ezekiel based on the measurements in the book. Inside the temple complex there’s an open top building which Tsoukalos contends was meant to hold the alien’s ship.
His big proof of this is the fact that Blumrich’s ship model fits into the area of contention very well.
