This may be the most fascinating episode I have seen - you have Randolph Churchill as the mystery guest, Desi Arnez on the panel, the third person ever to get a helicopter license who works for Bell Helicopter, and you have an advertisement for Univac and how it is being used to predict weather patterns. Fascinating episode
I posted on the original What's My Line channel that I wondered if Dorothy had anything to do with Desi and never got an answer let's see if I get one here
