On its maiden flight, America's first supersonic transport runs into deadly danger high in the sky and may never get to land. The plane is populated with Barbara Anderson, Bert Convy, Peter Graves, Lorne Greene, Tina Louise, George Maharis, Burgess Meredith, Doug McClure, Martin Milner, Robert Reed, Susan Strasberg, Billy Crystal, John de Lancie, and Regis Philbin. 
As Crow quips, "There are more stars in this movie than a two hour episode of 'Love Boat Goes to Fantasy Island'".
SST-Death Flight was originally developed under the title Death of the Maiden. This proved to be too similar to the title of pilot episode for the 1973 Jimmy Stewart TV series Hawkins - "Death and the Maiden". 
- In 1979 Universal Pictures released the similarly-themed The Concorde... Airport '79, which was such a commercial failure that it ended the popular series of Airport movies and served as a strong indicator for the decline of the disaster movie genre in general.
Cold Open:Joel and the bots sing "Has-Been Actors".
Segment One: Joel tries to disprove the theory that robots can't feel physical pain by administering electrical shocks to Servo. (Servo: "You can fill my head with gummi bears, but I won't talk!")
Segment Four: Servo and Crow read fan mail from "the babes." Servo invites viewers to write in with their favorite pizza toppings, much to Joel's chagrin.
- Portions of the theater segments were included on the MST3K Scrapbook tape.
- This episode marks the first time the crew of the SOL read letters from viewers (as opposed to listening to phone calls).
- The prologue with the Mads is later reworked into the prologue of Season 1 episode The Corpse Vanishes.
