I'm hoping that what I saw on that tape IS man-made, because that would mean that we have an operational space craft other than the aging Sapce Shuttle.
A very interesting issue.
Some contend ET's ordered us out of space--at least at the moon--because of our hazardous atomic stuff and general scrappiness.
Others contend that we have bases on the moon and on Mars and one of Saturn's moons--some our own and some in conjunction with ET's who taught us how to build the craft to get there.
Others contend that our reverse and taught engineering of UFO sorts of craft don't travel far, if at all, outside our magnetosphere.
