My memory is not very good so please excuse me. Back in the 1970's or 1980's there was a TV program on about UFO's. During this program they mention another TV program (1960's or 1970's) that was going to be shown but was canceled. This canceled program was going to show you the insides of a UFO and was supposed to be very detailed. I want to say that the canceled TV show was called "Project Rainbow" or something like that. But "Project Rainbow" has to do with the Philadelphia Experiment. The show was supposedly canceled abruptly and never shown or made mention of ever again. Does anyone remember this? Since watching SciFi's "Out of the Blue" UFO show it just popped back in my mind. If I remember right they showed a clip of the canceled show and there was some guy talking in the foreground and in the background someone or a couple was walking across a silver bridge in what looked like a UFO. I've been chasing this memory for 20+ years.
