Near the beginning, as Quincy and the unseen Sam circle the wreckage in the helicopter, Engine 51, the 1974 Ward LaFrance featured in EMERGENCY! is seen out Quincy's window. Unlike some other appearances of EMERGENCY! apparatus using stock footage, this was an original scene shot while 51 was quartered at Universal Studios.
The brief image of the Columbia Airlines plane at the beginning of this episode came from the movie Airport 1975.
