Location: The brief establishing shot showing the Los Angeles airport passenger terminal at the intersection of Airport Blvd. and Avion Drive appears to have been lifted, in part, from #96, TCOT Treacherous Toupee. That's actually Paul Drake and Dick Hart in the car. Posted by daveb, 3//2/10.

Location: Street numbers in Perry Mason episodes are usually real. Consequently based on the "12930" on he Bronson Aircraft shack and the overall topography I would say this location is probably 12930 Pierce Street along side Whiteman Airport in Pacoima, CA. Whiteman Airport is a small airport some Hollywood stars used which is tucked in the north east corner of the San Fernando Valley next to mountains which are visible in this episode.
