UFO/Flying Saucer Alias

BUR #13985 has been rejected.

remove implication flying_saucer -> spacecraft
create alias ufo -> flying_saucer

Previous topic #15759

I still stand by what I said back in that one.

I'm fine with implying saucer as spacecraft. However, not all UFO were in the shape of a flying saucer.

So, I'd like to have it the other way around; imply ufo to spacecraft, then imply flying saucer to ufo, since it's another type of UFO.
