I’m sorry to hear that. Klass was a rational voice amid the gullible and sensationalistic reporting you usually see whenever UFOs and aliens are brought up. I read his "UFO’s Explained" when I was in my early teens. That book, together with James Randi’s Flim Flam! and Larry Kusche’s Bermuda Triangle Mystery Solved influenced me to adopt an attitude of healthy skepticism toward fantastic claims that I still have today. They are also a good demonstrations of how most professional journalists have no idea what they’re talking about and don’t much care to find out…but that’s another post.
