In Search of..... show Video Clips
Note: "In Search of..." had no connection with OMNI. I have added this section because of the amazing things it has given to us as informed observers to consider just like OMNI did.

In Search off was a documentary show that ran from 1976 to 1982 with a short lived revival in 2002. Originally the show was hosted by Leonard Nimoy, then later on by Mitch Pileggi.

Also, There are some great listing details on the In Search of Wiki page.
Something that might refresh your memory would be Leonard Nimoy talking about the show:
"Lost Civilizations, Extra - Terrestrials, Myths and Monsters, Missing Persons, Magic and Witch Craft, Unexplained Pheonomenon, In search of Cameras are traveling the world, seeking out these great mysteries, This program was the result of work of Scientists, Researchers, and a group of highly skilled technicians"
The Assorted clips below are from various postings on YouTube. I thought it would be nice to have one spot to see them.
