In this episode, David McCallum guest stars as a Russian villain named Ivan who was once partnered with General Stockwell (Robert Vaughn). This reunited the two former The Man from U.N.C.L.E. (1964) stars. This was formatted in the same manner as an episode of The Man from U.N.C.L.E. (1964), complete with "chapter titles", the word "affair" in the title, and similar scene transitions. It is the last time that the two actors worked together.
When Stockwell is on the plane, he takes the phone and says "Open Channel D"-- a line used often in the Uncle series.
The team pose as air conditioning technicians from the company "Beller Air Conditioning" and wear overalls saying "Beller Air" on the back. In the season one's The Beast from the Belly of a Boeing, the airline at the center of the plot was "Beller Air". Stephen Cannell borrowed this name from his earlier series The Greatest American Hero.
The Bell LongRanger 206L-1 helicopter (N3886J c/n 45561) crashed and was damaged beyond repair 2/24/1996.
