Revealing mistake: While Hawkeye and Eddie are in the Swamp, when Eddie knocks over the stovepipe we can see that it's actually split into two pieces for the stunt, whereas in the previous shots it's not.
Visible crew/equipment: When General Barker opens the doors to Henry's office and finds Radar sitting behind the desk, we can see Barker's curved chalk foot marks on the floor beside the desk, where the actor will stand in a moment.
Continuity mistake: After uncovering the motorcycle, there's only the tan chicken around. A moment later, Ralph has a brown chicken in his arm that wasn't there before.
Continuity mistake: As "Ralph" gets the chicken off the tarp covered motorcycle, he goes to pick up the egg with his left hand. After the close up, he does it with his right.
Continuity mistake: When "Ralph" has Hawkeye and BJ at gunpoint, saving their lives, the scenery behind them changes several times. Sometimes there's the road and a few trees. Then there's no road and a lot more trees and shrubbery.
Visible crew/equipment: As Hawkeye, BJ, and "Ralph" come over to help the farmer, the shadow of the boom mike is seen on the ground at the bottom right side of the shot.
Visible crew/equipment: As The Bus nears Rainbow Bridge, there is a reflection of either the camera vehicle or equipment in the lower right side of the windshield.
Continuity mistake: When Father Mulcahy's finishing up his Sunday service with only Klinger, who's wearing a fetching red hat, there are nine stacked books at the corner of the table, but when it cuts to Mulcahy's closeup there are now only six stacked books (which will soon be used for the 11:00 Protestant service when Trapper and Hawkeye will pray for booze).
Continuity mistake: While Charles, BJ, and Hawkeye are in the Officers' Club, when Margaret storms in and starts yelling at Charles about the visiting pervert Colonel, Charles facepalms himself with his right hand, but next shot his left hand is up, and it continues to switch.
Revealing mistake: When Margaret whistles for the "third wave" she places Winchester's French horn on the ground, and there are three shots facing the jeep as it closes in on the horn - in the first two shots the horn's normal, but in the last shot the horn's already semi-squashed before the jeep even runs over it.
Continuity mistake: After Radar leaves the message with Stevens for Hawkeye's friend on the Essex, it cuts to Klinger removing a nut from the jeep and he's holding the wrench with his thumb at the top, but next shot he's holding the wrench the opposite way.
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: During Henry's home movies of Molly's birthday party, Lorraine brings out the cake with candles and sets it on the table, but the cake differs between the shots - note the writing.
Continuity mistake: In the mess tent, when Frank asks Hawkeye why he makes his life so miserable in the OR, notice that in the wideshots there's a silver pitcher, napkin holder, etc. On the table between Trapper and Margaret who are facing each other, but in the shots facing Margaret and Frank, and also Trapper and Hawkeye all of those things vanish and then reappear.
Continuity mistake: When Trapper turns around to ask Klinger for the status about the movie's sound, a small patch of his hat becomes wet from the roof's leaking, but in the next shot, his whole hat is instantly soaked. (00:01:55)
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.
