Continuity mistake: Before The Sniper starts firing, Hawkeye is carrying the two bottles of scotch firmly gripped by the necks. A second later, he's barely holding them by the caps, in preparation to drop them.
Other mistake: Frank Burns states when he is talking to a patient who just got a purple heart, that he would like to get a purple heart, but in the earlier episode ‘The Kids', Frank Burns received a purple heart due to a injury, and in the S1 episode ‘Sometimes You Hear the Bullet', Frank Burns gets another Purple Heart. Despite them both being stolen, they still count on his army record.
Factual error: As Hawkeye, Radar' and BJ stop to change the flat, Hawkeye uses a scissor jack to raise the Jeep. However, the scissor jack was not in use for this model of Jeep.
Visible crew/equipment: When Margaret listens in on Frank's phone conversation with his wife, Margaret throws a chair at him and storms out of the office, and after she calls Frank a chinless chipmunk a boom mic dips into view at the top, left corner of the screen.
Dear Mildred - S4-E7
Continuity mistake: When Colonel Potter's in his office finishing up his letter to Mildred, right before Margaret, Frank, and the others walk in, the things on his desk change their positions between shots - such as the paper tray moving from Potter's left to the right side of his desk.
Continuity mistake: After Jack wins a drink from Hawkeye and BJ, Hawkeye grabs the orange to inspect it for tears to prove his magnet theory. After the angle change, he grabs it again.
Visible crew/equipment: When the camera angle changes to look at the cover being put over the soldier's head, the camera is briefly reflected until the cover is locked in place.
Continuity mistake: As the interviewer talks to Hawkeye, his hand alternates from just below the microphone head to just above the bottom end between angles.
Dear Peggy - S4-E10
Character mistake: When he sees the 'P' for Protestant on Davis' chart, Col. Hollister states "A lot of your Davises are 'J's, you know" implying that Davis is a Jewish name. In fact, the ID tag code for Jewish faith was 'H' for Hebrew. (00:18:45)
Dear Peggy - S4-E10
Audio problem: As Hawkeye calls for X-rays, you can see Klinger hollering a reply through the door, but nothing is heard. (00:21:30)
Continuity mistake: When Carly is talking about Hawkeye being a "mortician's delight", she is gesturing with her right hand, and it's about waist height at the end of the motion. When the camera goes to a wide shot, her hand is up by her chin, about eight inches from her face.
Dear Mildred - S4-E7
Revealing mistake: In the shot where the horse kicks in the door, there's actually two shots - a kick, a quick cut, another kick. If you look closely, you can see how the hoof of one of the horse-leg props breaks off during the first kick. The second kick is performed by one leg only. If you look really closely - and probably use the slow-motion function - you can even make out the hand of the one wielding the leg through the hole made in the first kick. (00:18:10)
Dear Mildred - S4-E7
Continuity mistake: In the episode when Radar gives Potter the horse, they keep referring to the horse as "he". In later episodes, the horse is a mare named Sophie.
Other mistake: As Burns, driving the tank, runs over the Swamp, there's no sign of the still anywhere.
Continuity mistake: In the Commander's office, Frank's arms go from being in front of MacArthur's picture frame, to gone, and back again in a matter of a few seconds.
Other mistake: In the opening, when the flags were raised, the United Nations flag is hung upside down.
Character mistake: When Frank is berating Igor about the food on the trays, he calls him "Sergeant." Igor has always been a private.
Answer: The C-42 was a military variant of the Douglas DC-2. Very few C-42's were built, so it's questionable that Potter would specifically have seen that particular model, but, given his military background, it's not entirely unreasonable that he might use the military designation even when the aircraft in question is actually a civilian DC-2.
