This episode does NOT include Sandra Spence as Whirlybird secretary Janet Culver as shown for this episode. This is the debut episode for Nancy Hale as secretary Helen Carter who would remain in that role for the balance of the series.
Interesting trivia about this episode is that several sources have Aztec Treasure as the title for this episode yet there is no known reason for that mistake. This is similar to the unsubstantiated reports that The Whirlybirds was renamed Copter Patrol in syndication. The series was always a syndicated show produced and sold by Desilu productions, it was never a network show, not even with all the clout of Desilu at CBS.
