We learn, seventy years after the fact, that the defense industry has been unable to learn anything at all from the assailable remains of UFOs. We also learn that a witness who carefully inspected one of these crafts saw no sign of an identifiable power plant. The immediate take home is that none of this contributed much of anything to our own special craft programs.
Thus my identification of gravity manipulation beginning back in 1955 at least may well be all we have and that was derivable from Tesla's work. We also have observed that alien witnesses tell us only what we already know. This also tells me that we will have to discover usable time wormholes by ourselves.
We ourselves will transition into a much more capable second tier matter entity and that should mean having the ability to craft a personal UFO using our minds alone through intent. Recall we manipulate our own bodies to some degree already and this simply needs to be powered up.
In the meantime the industry has merely used all this to drum up research contracts signifying nothing for decades. I already knew as much decades ago in terms of tangible results. This merely confirms their abject lack of progress.
