‘We now have the technology to take ET home.’ -1993 speech before UCLA alumni by Ben Rich, director of Lockheed’s Skunk Works from 1975 to 1991. Does the US have advanced, 'UFO type' space flight technology?

Obviously Ben Rich is a man who knew a thing or two about the cutting edge of aerial vehicles. Of course, being top secret programs, he was very limited in what he could say about what has been developed, but his comments were intriguing. Considering how far the rest of technology has progressed since then, it makes me wonder how far they've taken that technology? Could humans already be traveling to distant worlds in secret, black budget military programs? If so, how long will that go on before it becomes public knowledge?
