The book "Unconventional Flying Objects" by Paul R. Hill has some descriptions of possible UFO technology.

Could you Imagine if you went back to say, King Arthurs Court, handed them a Cell Phone , and asked them to explain how it works.
Thats the same as asking us to explain their Mode of Travel.
We can offer Intelligent Guesses , based on our Tech, but Answers, not so much.

That isn't true. There has been a near step change in the scientific understanding of the physical world from 1700 to now, with maximum slope between 1880 and 1940.
In 800 AD, humans knew absolutely nothing actually true about the physical structure of the world.
Today, humans know a tremendous amount of experimentally validated facts about physics and chemistry of nearly everything which can be touched in the solar system, and have inferred things about distant celestial objects with extremely exotic and dangerous states of matter, all based on physics derived in Earth-bound labs. That's pretty spectacular.
We know why stars look the way they do, we can predict the distribution of star masses & colors, we know why they blow up. We detected freaking neutrinos from a supernova. People predicted how something as insane as a supernova worked, and then detected the actual smoking gun particle (neutrinos from massive fusion wave), directly on earth with heroic instrumentation.
We could talk physics with ET far better than Merlin .
Text --- Source: Wikipedia "Envelope [Waves]" ---"In condensed matter physics an energy Eigenfunction for a mobile charge carrier in a crystal can be expressed as a Bloch wave. For example, the wave function of a carrier trapped near an impurity is governed by an envelope function F that governs a super position of Bloch functions.
In a medium such as classical vaccuum the dispersion relation for electromagnetic waves is w=CoK where Co is the speed of light in classical vaccuum. For this case the phase and group velocities both are Co. In so-called dispersive media the dispersion relation can be a complicated function of wave vector, and the phase and group velocities are not the same. In the general case, the phase and group velocities may have different directions."ex]
Text --- In a plasma the free electrons constantly produce Bremsstrahlung-[ i.e. "braking radiation" or "deceleration" --- is electromagnetic radiation produced by a charged particle when deflected by another charged particle, typically an electron by an atomic nucleus.] --- If the plasma is optically thin the bremsstrahlung radiation leaves the plasma, carrying part of the plasma energy. The moving particle loses kinetic energy, which is converted into a photon because energy is conserved.
