Other mistake: In the interior shots of Station 51 (the studio set), when facing the rear apparatus bay door, the right wall has a door to Captain Stanley's office, a very large map, the radio receiver base station where they respond to dispatch, the kitchen doorway, and a double-door closet, that's it. However, when Station 51 is shown in the exterior shots (the real Station 127 aka 51), as either the engine or squad exits when the apparatus bay door is up, we see that the right wall has many more doors on that wall. Additionally, the opposite wall on the set has only two doors - one to locker room/bathroom, and one to the dorm, however at the real 127's, that wall has three doors - two of them are to the dorm.
Other mistake: On Emergency! there's a noticeable lack of blood (not that it's a bad thing), even on the medical disposable gloves, during numerous scenes such as when a victim has arterial bleeding from carotid, brachial, and femoral arteries, or during the surgical procedures, and the labor/delivery scenes.
Other mistake: There are two specific pieces of stock footage used from season 3 onward, when the camera faces the fire station, it shows either just Squad 51, or both Squad 51 and Engine 51 pulling out of the apparatus bay, then turning left (viewer's right) onto E 223rd St, and the real Station 127's Truck 127 can be seen parked in the side driveway. Examples are: In season 6, "The Exam", when Squad 51 responds to Molly's phone call, and in "Hypochondri-Cap", when Station 51 is dispatched to an 'unconscious female in a car'.
Other mistake: When the plane crashes into the neighborhood and traps Gage and DeSoto in the house, you see outside shots of the squad when the other two paramedics arrive. You can see a large piece of smoking engine/plane laying on the back end of the squad, right over the spare air tanks. They would have exploded when something that heavy and hot landed on them, since they are filled with oxygen. The tanks would be full or they would not be on the back of the squad.
Suggested correction: Probably air tanks, because oxygen tanks are always painted green. Both kinds of tank are very tough. Hard to tell with how much force the plane debris might have landed except that the truck still looks pretty much intact. However, if the plot required it, I would find it completely believable that the crash could have exploded the tanks, but also don't find it strange that they didn't explode.
