Revealing mistake: During the rescue at the jail, while Roy tries to get a safety belt around the prisoner's waist, the man freaks out, then grabs Roy and they both swing out on Roy's safety line. When the camera pans a bit too far to the left, we can see the edge of the fake "sky" screen on the left, behind the building's replica set used for closeups.
Revealing mistake: On the roof of the jail, Roy buckles his safety belt around his waist, with an extra belt for the prisoner hanging from it as well. When Roy removes the second belt from his own, we can see two carabiners that are now attached to his lifebelt, which go down into Roy's pants. Those carabiners are presumably attached to extra support under Roy's pants.
Revealing mistake: After the husband and wife are pulled from the plane wreck, they're lying on the ground while Roy and Johnny are treating them. In this wide shot, which lasts about 12 seconds, Roy has no eyes or eyebrows, as part of his face has been blurred out, and when Roy moves his face it's quite bizarre to look at. This is visible on Netflix as well as the DVD, which was created in 2010 by Universal Studios, where Emergency! was filmed during its run on the air in the '70s.
Revealing mistake: At the structure fire at an abandoned building, when Engine 164 arrives we see that it has distinctive markings beside the driver's side door and tire rim. When Engine 72 arrives the same markings are in the same place, revealing that it's the same engine and they used different magnetic number decals for the engine.
Revealing mistake: When Station 51 is dispatched to "plane that hit building," after they rescue the two aboard the plane, just before the explosion when the orange combustible drum is propelled into the air, we can see the stunt's projectile to get the drum airborne.
Revealing mistake: At the site of the hang gliding accident, just after the glider falls, in the long shot when Johnny and Chet pull the unconscious victim higher on the cliff, the victim is supposed to be unconscious, yet we see him use his right leg to push himself higher up to help John and Chet pull him up.
Revealing mistake: When Station 51 is dispatched to the hang gliding accident with two men trapped on a cliff, as the squad and engine roll out of the bay, we can see the real 127's vehicle is still parked in the apparatus bay, near the rear door.
Revealing mistake: During the rescue of the two mountain climbers who are stuck on the side of a building, when Johnny and Roy are hanging from the lines which are attached to the lifebelts buckled around their waists, we can also see that attached to their lifebelts are carabiners, which are tucked inside their shirts. Those carabiners are presumably attached to extra support under their clothing. Johnny's is particularly visible, while Roy tries to cover his carabiners with his hand.
Revealing mistake: When Station 51 is dispatched to "accident with injuries," en route one of the camera angles is from the POV behind Roy and John, where the back of the squad is located. The problem is that there's bright sunlight on their backs as they’re driving, when it shouldn't be there. Artistic license is acceptable, but having so much sunlight where it should not be reveals that Squad 51 is not in its normal state.
Revealing mistake: When John and Roy reach the man lying near the pool with a back injury, while Thadeus keeps gnawing and grabbing at Roy's pant leg, we see the extra material that Roy has under the pants (over his socks) to prevent the dog from accidentally harming his legs.
Welcome to Santa Rosa County - S6-E10
Revealing mistake: After rescuing the burn victim from The Boat's explosion, Johnny and Roy are at the back of the camper with the victim, while the victim's wife drives the camper to the clinic, but when they arrive at the clinic the camper hasn't even stopped yet, and we can see the woman's legs at the side of the camper, waiting for her cue to come rushing to the camper's rear door when her husband is brought out.
Welcome to Santa Rosa County - S6-E10
Revealing mistake: While in Santa Rosa County, after Roy and John rescue the two injured rock climbers, and also later after they rescue the burn victim from the lake, the Richards ambulance that transports the patients has license plate number "Z125631" which is pretty funny. That plate number should look familiar, as it's the same plate number on the ambulance in LA County, seen in many episodes such as "Rules of Order", "Unlikely Heirs", and "Not Available."
Paper Work - S6-E11
Revealing mistake: After Roy and John meet the new supply nurse, when Squad 51 rolls back into the station the license plate number on the back of Engine 51 ends in 174, but the engine's plate number should read 999058. Engine 127's license plate number is 180174.
Paper Work - S6-E11
Revealing mistake: At the start of the episode, when the camera zooms in on the words 'Los Angeles County Fire Station 51' which are attached to the side of the building, we can see that this shot is actually played in reverse - notice the cars/trucks behind the station are driving backwards. Additionally, note that the real 127's rig is seen in the driveway to the right. Also interesting to notice are the upper/lower metal bars which are attached to the bricks, where we can see the bars are much longer after 'Station 51', with a space for something missing, due to the fact that is was made to hold '127' on it.
Revealing mistake: At the gas station with the broken pump nozzle, Captain Stanley and the station attendant head to the garage area to see the main shut-off circuit box, which is located at the far right corner of the garage, but in the next shot, we can see the attendant's reflection behind Roy, and he's standing somewhere else off camera, not where he's supposed to be in the next shot with Captain Stanley.
Revealing mistake: At the gas station, when the pump sparks and catches fire, we can see that it's not gasoline on the ground with the water from the fire hose, but instead it's floating thick gobs of stunt fire gel with burning flames.
Family Ties - S6-E16
Revealing mistake: When the fire is started in the patient's room, which is caused by liquid shorting out the clock radio, at the end of the hallway we can see through the window's open shades and the view right outside the window is quite pretty, but in all of the exterior shots of Rampart there is no such view on any of its sides. It's a matte painting.
Bottom Line - S6-E17
Revealing mistake: While the guys are eating chilli at the table, when Station 51 is dispatched to 'man down', notice that when they're at the scene, both paramedics are wearing their jackets and Johnny is wearing his helmet. We never see Johnny's face in any of the wide shots, because the entire time it's the double with Roy. We only see Johnny alone in a few closeups, pickup shots which were filmed later, and we can see the style of the houses in the closeups do not resemble the houses in the other shots. The real Johnny is back, once they reach the hospital.
Revealing mistake: When Station 51 is dispatched to a man trapped at World Picture Corp, just as they reach the entrance to World Picture Corp, the Sheraton-Universal is seen on the corner, and the street sign for touring Universal Studios is visible as well. (00:19:45)
Revealing mistake: At World Picture Corp, when John and the guy with the broken clavicle are lowered from the overhead joists they're both wearing lifebelts buckled around their waists. The problem is that once they reach the ground, we can see the additional carabiner attached to John's lifebelt, which is also attached to extra green support protruding from under John's shirt. We can also see the victim's additional carabiner going under his flannel shirt. While Roy is on the line with Rampart, when John removes the victim's lifebelt, the extra carabiner is still protruding from under the victim's shirt and John places his hand over it. (00:27:00)
Answer: It is standard practice to wet down driveways so that they stand out in a long shot.
