The fire station responding is the same one that's in the TV show emergency. It is unclear if Gage and Desoto are on duty for this call.
The plot of this episode is to kill the character Tony Eagle, played by Ricky Nelson, in a plane crash. In an ironic twist of fate Ricky Nelson ended up perishing in a plane crash 8 years later.
Ricky Nelson also played a character named Tony in The Flickering Torch Mystery (1969) on The Hardy Boys (1969) animated series that aired on Saturday mornings on ABC from 1969 to 1971.
"The Flickering Torch Mystery" book was published in 1943. In it, the Hardy Boys investigate two mysterious plane crashes that have already occurred, unlike the tv show where Frank and Joe are trying to prevent one from happening.
