Gage and Desoto go downstairs from fighting the fire to join the parade. However, when they get downstairs, the fire is out and the street is completely peaceful and dry with no activity or other firefighters.
When Roy & Johnny are on their way to the parade, and then the fire, the view switches from a camera on the front of the vintage engine to one on a camera truck. In the close-up, it can be seen that they are in the right lane of a two-lane road. The view from the camera truck shows them in the left lane.
When responding to a heart attack, the address given is 4738 yet the building across the street has an address of 10486.
At the beginning the paramedics aid a heart-attack victim, but he refuses help. He then tries to start the Ford car he is in. The sound of the car starting is actually from a Chrysler product. During the 70's , car engines had a particular starting sound per car company.
When Gage and DeSoto climb to the roof, it is only a few feet wide, revealing that the building is a studio facade.
When Johnny and Roy leave the station in their antique engine they turn right, and eventually go to a structure fire. When station 51 responds to a structure fire where Johnny and Roy are, they turn left, in the opposite direction.
When following the sick man at the beginning, Roy runs a stop sign (they are not driving with lights and siren on).
