Fromtheskydown makes a good point about it's size from our own 'current' technological and engineering point's of view but you are absolutely
correct there is no reason that a structure would be as small as our own current ability's would limit us to.
Indeed you would imagine for a truly long distance craft that may have to serve many generation's if it was limited to below light speed or if it had
to travel super vast distance's then the bigger the better and even entire world's aboard ship's is a practical concept and of course these multi
generational star ship concept's are a stape of many sci fi author's.
Also if the craft rotated around it's core and was disc shaped then you could envisage it as a short cylinder rather than a disc whose rotation
provided centrifugal force to replace gravity on multile concentric deck's arranged around it's core.
Our own ability's at least potentially though restrained by the controlling and corrupt elite who currently curtail our world for there own benefit
and to keep us in our place do potentially have the ability to open up all kind's of future project's of massive scope.
Imagine automated three dimensional printing systems and robotic assembler's producing such a ship or object of such size in modular section's in
orbit or even floating on the ocean like an artificial island, all that they would be limited by is the availability of resources and the plan's for
the structure or craft.
Personally though I don't think this is a UFO though I would like to be wrong, then of course the old addage look at how the mighty are fallen would
be most applicable.
One other factor a large craft or structure in space would be more likely to be hit by space object's but it would also be more likely to survive
such impact's, 20 miles is actually rather small except by our own current ability's if you think about it as well and not knowing what propulsion
technology's would be used we can not say how it would handle in a planet atmosphere, if our race survives and we shrug off the elite whom are seeking
to farm us and control our numbers like a slave species to keep themselves in power then the human race given a unifying cause can achieve
unbelievable feat's and of course if that unified race then has this type of technology what can it then achieve for good or ill.
