I came across this transcript of a chat with Robert Stack on the Lifetime website from 2002. It was an interesting read as they asked him a lot of questions about UM and thought you guys might enjoy reading it too:

Thanks for that info. I've have also read this before the link was posted here. It is very intresting. I wish I could have been there.
