Stalag 13 Theatre on the Air is a term first used by Colonel Hogan in the episode, Top Hat, White Tie and Bomb Sight, in reference to the radio show that he and the others were soon going to use against Kommandant Klink, who had just 'secretly' placed a few bugs inside Hogan's office, thinking that was where the prisoners would plot their escape attempts. The prisoners' faux show was conducted to help get Hogan out of the camp and to the Hauserhauf hotel in Hammelburg so that he can pass along to Willie, an underground agent who was working at the hotel as a waiter, a coded message from London warning him to not appear at the next weapons drop, as the Germans may have set up a trap for him.
