At the start of the first response from Station 10, the SCU tones played to notify Station 10 are those that are used for Station 51 in all other episodes of the series. In addition, when Station 51 is called out later in the show, the SCU tones for that call are different from the balance of the series.
In this flashback episode, of the TV pilot movie, Johnny tells Roy that he was working B shift at Station 8. However, the station and companies are listed as station 10.
In the second hour, the paramedics discuss with Dixie McCall a heroin overdose case that was just brought in. DeSoto mentions that the OD was a "...post-graduate mainliner. Sheriff's follow-up found two balloons of hash in her pocket." Hash is a derivative of marijuana. It is smoked, not injected, has no relationship to heroin, and is seldom distributed in balloons, as heroin is.
When Gage and DeSoto are aiding in the rescue of the miner trapped under the tractor and the tunnel wall collapses, several rocks can be seen floating on the water, obviously made of foam or some similar material.
In The Flashback Episode The Squad Was Returning From A Run. In The View From Outside The Station The Engine Is Gone. But As Johnny Was Getting Out Of The Squad and Entering The Day Room The Engine Is In The Station Bay.
In the intro, four SCU tones are sounded for the factory fire. Since 7 units are summoned to the fire, with 5 of them being in Station 10, there should only be a maximum of 3 stations responding to the fire, and therefore 3 SCU tones.
When Gage was called to the electrocution on Squad 10, one SCU tone was sounded. Since Truck 127 was also summoned from another station, there should have been another SCU tone.
When Station 10 is dispatched to the factory fire, two fire officers look at the map and then bump into each other on the way to their rigs. While this was likely an unintentional effect of the improvisation in that scene, it adds realism to the chaotic environment in the station at that moment.
In the very first scene, the squad is backing into the station and there is no fire engine in the bay. When the camera joins them in the bay, as Johnny exits the squad, there is a fire engine there.
At the very beginning of the episode, a crew member can be seen at the right of the screen. He is standing near the right side of the rescue squad's hood by the wall.
During the factory fire, the shadows of the camera operator and boom mic technician are visible in some shots (probably to give a "live news" feel).
When Station 10 is responding to the factory fire, they pass an unlit cinematic spotlight by the side of the road, visible on the left.
When Dr. Brackett looks at the letter inviting him to Sacramento, the hospital's address is "Carson City, California". Carson is in Los Angeles County, California; Carson City is the capital of Nevada.
Early on, Dixie McCall is established as a former military nurse who had served in the Korean War. Later, when she is injured during a rescue, Johnny tells Rampart her age is "approximately 30". The Korean War lasted from 1950 to 1953, which means Dixie would've only been between 9 and 12 years old at the time of the war, far too young for military service, let alone as a nurse. Her correct age should've been closer to Julie London's actual age of 45 at the time this episode aired.
When the paramedics are lined up at their graduation, standing at the far end of the group is Marco Lopez. He's not identified and in all the subsequent episodes there is no mention of his ever being a paramedic.
