It seems like an excellent start for a new year.
OK lets assume for the sake of nonargument that your information is correct and accurate and there is and has not been any "flying saucers" or their occupants zipping around in space.
Then all UFO's are explainable or fiction.
Fiction originates from "imagination."
Back in the days when the original Star Trek TV series was made, the hand held prop "communicator" that was used in the stories, was simply "imagination," today we have similar devices that are called cell phones.
Without "imagination" it is impossible to make something that is completely new, in fact it is not even possible to "improve" existing devices without "imagining" how they could be made better.
When I wrote that:
Years later I purchased the book and read all of it, this time it made much more sense.
It should have read: Years later I purchased the book and read all of it, this time several things, including the drawing, made much more sense.
The drawing and some other things made much more sense because some of the things that were "imagined" in the book were by then actually being manufactured and used in reality.
You did not comment on the "scientific" part of the "imagination".
I figure that if a "saucer" shaped craft was constructed that had a 30 foot diameter and IF it was possible to eliminate all the air from the top of the "saucer," then the air pressure from the underneath would be able to "support" or "float" a weight that is more than a million pounds. (I do hope that you do a more accurate calculation of the weight and pressure ratios involved.)
In any case, I for one, would like own a craft that is able to fly around the moon so I could see for myself what is on the other side. :-)
