The 'N' in the aircraft's registration number has been masked to disguise the fact that it is a US registered airplane. The full number, N33BK shows it as a British Aerospace 125 and is currently (2017) deregistered.
This show is the fifth and final guest star role for Anthony Zerbe.
The intro of the mission uses a record player instead of the usual tape recorder/player. At end of the message, the vinyl record "self destructs", one of the few times a reel-to-reel tape player isn't used.
The plane used is a Learjet 24. When in the cockpit the words "Lear 24" are on the control yokes.
The only episode of the season requiring our heroes to venture outside the United States, "The Connection" is also Mission's most geographically encompassing story. The action takes place on virtually four different continents, with many characters shifting location as events warrant.
