but Captain Cook and Lord Nelson could have understood the CONCEPT of an airliner if someone who knew the principles were there:
"See, it's like a big bird with a flaming asshole, made out of a funny metal like iron, only lighter."....etc. And we could have made wooden & paper models to demonstrate gliding...etc..

There nothing much about a plane that required concepts alien to the the mind. Faster than light travel is another deal altogether. Sc-Fi writers and theoretical physicists play with concepts that they think might have meaning, but no one is sure yet if is more than clever linguistic creativity. Accelerating a solid body past the speed at which it attains infinite mass, ot bypassing that situation altogether does not necessarily work, just because we can say the words.

It IS a fascinating idea, and I HOPE it is someday possible, but it is hardly the basis for serious claims about other experiences.

One neglected, but important rule of logic is "from false premises, anything follows."
