One of the many ways UFO craft have shown vast superiority over human made craft is their ability to become invisible instantaneously. Just ask Cmdr. David Fravor who along with three other Navy personnel witnessed a Tic Tac disappear before their very eyes during the Nimitz encounter of 2004. Obviously any country possessing this ability would have a distinct advantage during a military conflict. North Carolina State University has been developing a ceramic coating which may indeed create a degree of invisibility and you can learn more about this interesting development from author Christopher Plain writing for The Debrief HERE.
