Revealing mistake: While John's in the ambulance with the boy who ingested the poison, after John inserts the esophageal airway and uses the ambu-bag, just as John says, "Real good," if we look out the window behind the attendant, we can see Universal's GlamourTrams (a set of three trams) driving by in the distance. The footage inside the ambulance was shot while the ambulance drove around Universal's lots.
Revealing mistake: After Paula's car door is pulled open, when Roy leans her head back in the shot from behind him, we should be able to see out the right rear window, but the view has been deliberately blacked out from this POV.
Revealing mistake: When Roy and Johnny are in the radioactive lab, loading the unconscious doctor with severe radioactive poisoning onto the stretcher, note that the unconscious doctor is lifting his own left arm, and moving it onto the stretcher so it's resting beside him properly.
Revealing mistake: At the house fire, after Roy and Johnny go upstairs to rescue the invalid woman, Captain Stanley and Chet head to the front door, and just before Cap kicks in the front door, we can see that the door isn't actually closed, it's just ajar.
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: When Station 51 is dispatched to 'man trapped', just as Engine 51 rolls out of the apparatus bay and heads down the driveway, the real 127's vehicle is seen parked inside the bay, near the rear door.
Revealing mistake: After Station 51 is dispatched to the 'plane in trouble' it becomes a plane crash rescue and recovery, and when they pull out the pilot's body, who they said died on impact, his right hand moves to clasp his left wrist, and he also bends and moves his leg.
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: When Johnny climbs up to the roof to get Sheba down, Johnny has two long shadows, one from the sun and one from the set lighting.
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.
Revealing mistake: At the structure fire, when Engine 9 and Engine 17 roll up, we can see the large, red, rectangular vinyl material that is adhered to the front of the engines, with their company numbers printed on it. Additionally, the red vinyl material adhered to the top of 9's and 17's cabs, which cover their real company numbers, flap up in the wind.
Revealing mistake: When Johnny and Roy are in the storm drain searching for the two missing boys, all the walls have very distinctive water stains and markings, and the same walls and drains keep repeating, no matter the distance they have walked.
Revealing mistake: During the structure fire in the middle of the night, when Roy rescues the little boy and the dog from the burning house, it's too obvious they are a doll and stuffed animal.
Revealing mistake: On scene with the little girl trapped in the hole, when they shine the flashlight down the hole in the overhead closeup, it's too obvious that it's a doll with its arm raised up, plus the fact that we see plenty of space around the doll, contradicting the plot of the little girl being wedged in a tight space.
Revealing mistake: When Johnny and Roy are on the schooner, with the unconscious man hanging upside down from the mast's rigging, as they pull the man up the safety harness around the stuntman's ankle is visible.
Nurse's Wild - S1-E7
Revealing mistake: When John and Roy get back to the station and are discussing the cardiac patient they brought to Rampart earlier, the usually highly reflective passenger spotlight has been sprayed with a dulling spray, to temporarily dull the surface.
Revealing mistake: When the boy is discharged from the ER and is reunited with his dog, John and Roy are standing near the squad watching the reunion, and the usually highly reflective surface of the passenger side spotlight has been sprayed with a dulling spray, to temporarily dull the surface.

Revealing mistake: When Johnny and Roy are at the top of the open drawbridge, Johnny is wearing a watch on his left wrist, but when his stunt double rescues the woman in the car dangling off the edge, he is not wearing a watch. Additionally, the stuntman's pompier belt has a large axe sheath attached to it, but Johnny's life belt does not, and the stuntman's arms are much hairier, as usual.
Revealing mistake: When Station 51 is dispatched to the chimney explosion, en route there is a moving bird's-eye view as the filming chopper follows 51's vehicles making a right turn. On the ground below, there are two people standing beside a blue station wagon, and one points up to the chopper flying overhead.
