Several memories
I recall this show as well but I only have a few memories.
I recall one episode ending with the debunking of a UFO being that it was someone with a helicopter using wires to hold up the UFO and using a remote control to open a flapper door on the bottom of the UFO to release sparkling dust. I can't remember if it made a noise but I can't believe people wouldn't hear a helicopter.
Another one that has stuck with me, and spooked me pretty good at the time (I was 8) is at the end of an episode a little boy is telling one of the investigators of how he came upon a UFO on the ground and it put down a ramp and down came this thing which I think was more of a robot than alien and it spoke to the boy, and the voice it used was really spooky and chilling.
Be great to see this again. I've always wondered if some of the X-Files people knew about this show as they are both similar to each other in ways.
