Strange UFO Stories

I was just checking to see what was on TV and I noticed a show on the Discovery Channel called Strange UFO Stories. I don't know if anyone has seen any of these shows (They are marked 'Repeat' but I have not seen them)

It's a marathon session as these shows are on from 6:00 p.m. Sunday evening to 6:00 a.m. Monday morning (my time, Ontario, Canada). Too bad I won't be able to watch all of them; it does look very interesting. The one they have on now is about alien gateways into other dimensions, including ours. They were mentioning Rosslyn (sp?) Church in Scotland.
