Johnny Rodriguez, who appeared as the motorcycle rider who struck a pedestrian, is a country music artist who had a string of hits in the 1970's and 1980's. He was credited as a special guest star in this episode, and this is his only credited acting role to date.

This episode ends with a Jack Webb voiceover: "Next week, the conclusion of 'Air Support'"

In a bit of interesting casting, Rachel Romen, who portrayed the woman who Malloy correctly suspected of murdering her mentally disabled husband, previously portrayed the wife of Malloy's slain best friend in the Season 3 episode "Elegy for a Pig."

In a rare, but glaring, directing error, Malloy and Reed fail to handcuff the gas station robbery suspect until after they question him, despite the fact he had just led them on a dangerous high speed chase and was suspected of shooting at the attendant.

The sound of a moving traincan beheard prominently during the chase scene at the rail yard, but it is obvious from the different camera angles that there isn't a moving train.

This episode concludes with a title card reading "To Be Continued in Part II", and a voice over by Jack Webb: "Travel with Officers Reed and Malloy, as they continue their ride with the commissioner."

Leo Gordon is credited as the writer of this episode and also plays the role of the fugitive at the hotel. His wife, Lynn Cartwright, also appears in this episode as the woman who is suffering from withdrawal convulsions in her car.
