Story Notes

 * This is the thirty-first produced episode of the series, but is the twenty-ninth episode to be shown on television.
 * Larry Mann (Doctor Vanetti) is known for his work as the voice of "Yukon Cornelius" in Rudolph, The Red-Nosed Reindeer.
 * A rare use of impossible sound effects is displayed in this episode: As Hogan leaves Klink's office and fingers the arrow in the door, an external "boing" sound is used to accentuate the action.
 * A mythical figure is mentioned in the episode: Robin Hood.
 * This is the second series appearance by Colonel Crittendon (Bernard Fox). It is at this time that he learns the truth about our heroes.
 * This is the only time any plan by Colonel Crittendon comes close to succeeding!

Timeline Notes and Speculations

 * Dr. Vanetti was Enrico Fermi's classmate at the University of Göttingen in 1924, as referenced in the episode.
 * A date sometime in the spring of 1944 appears to be implied.
 * This takes place before Two Nazis for the Price of One, as our heroes do not as yet know anything about the Manhattan Project.
 * This is the second time that Hogan demonstrates some knowledge of atomic research and its implications. The first was Go Light on the Heavy Water.
