Government secrets? Or just another conspiracy theory.

Well they are like the only super power on earth, and have all the advanced shit. Alot of it could be military planes etc that they don't want people to know about, or other stuff

True.

But why is it only in the last hundred or so years are they now just getting 'sighted'? I don't think they have any 'sightings' from before aircrafts were invented, or at least don't know of any recorded possible findings.

Aircrafts are only like 105 or something years old, so surely people must of gotten curious when they see things flying through the sky and couldn't see if it was a comet or anything, yet when there have been possible sightings it's near America.

And wouldn't Japan be advanced enough to have sighting claims? Or somewhere in the poles where scientists go to get away from the light polution?
