A special investigation in which Tony Harris uncovers what NASA really knows about UFOs--and what it may not be telling us. Could a mysterious object from outside our solar system actually be alien technology? Did NASA conceal evidence of a UFO photographed during the Gemini 11 mission? Was a strange triangular object seen on a live International Space Station feed proof of a cover-up? And did hidden NASA archives preserve images the public was never meant to see?
