I have read in a few places(that frankly must be taken with more than a few grains of salt), they(craft/beings) manipulate gravity with incredible force. There is a "slow" speed method of hovering travel, and another phase-shift slingshot method. It has been reported that the beings both do not and DO feel relativistic effects(anywhere from 100s of years to a few months). It is hard to cut through misinformation on this subject for very obvious reasons. Basically - wow ZOOOOOM ZOOOM, is all anyone can really say about it.
Ok.. .. .. this looks like fun.
How would you design a UFO-like spacecraft... what things would you use?
I'll think about it for a while and post a hypothetical design. I know draqon would enjoy this, stidying aeronautics and what not.
