As You Were - S2-E20
Revealing mistake: At the end, in the shot of Klinger singing while he's sewing a dress on his White Rotary sewing machine, as he's guiding the fabric forward it isn't actually under the machine's presser foot, which it needs to be in order to be stitched by the needle.
As You Were - S2-E20
Continuity mistake: When Klinger's in Father Mulcahy's tent he pulls up a chair and when he sits down he places his purse on his lap, but in the closeup the purse strap is now around his left arm.
Adam's Ribs - S3-E11
Continuity mistake: While Hawkeye leads the protest in the mess tent shouting "we want something else," there are two closeup shots of the table where Klinger and Radar are seated, and Klinger's white evening purse is missing, but in the previous and following wideshots the purse is hanging on his arm.
Adam's Ribs - S3-E11
Continuity mistake: When Hawkeye's in the mess tent holding the food tray the succotash is on the left and potatoes on the right with a space in the middle, so when Igor serves him creamed corn offscreen the corn should be between the potatoes and succotash, but when Hawkeye's having the fit and walks away from Igor, the potatoes (a higher mound) are now in the center space between corn and succotash.
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.
For the Good of the Outfit - S2-E4
Continuity mistake: Hawkeye mails a letter to his father which is delayed in its delivery, and when Hawkeye finally receives a reply from his father it's dated May 24, 1951, but in the previous episode "Radar's Report" the weekly report that Radar typed up was dated October 17 through October 22, 1951.
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 the Swinging Surgeons are performing during the charity no-talent night, Radar's drum kit is set up differently between the wideshots and closeups.
Henry, Please Come Home - S1-E9
Continuity mistake: When Henry's being given the Special Citation of Merit - 4th class, in the wide shot of Hawkeye and Trapper there's dark facial stubble on Hawkeye's face, but in their closeups there's barely any stubble on his face.
The Sniper - S2-E10
Other mistake: When Hawkeye and Trapper make Frank up to look like MacArthur, as they put the pipe in the "sleeping" Frank's mouth, he opens a bit wider, and bites down on the stem, then says his last line of the episode.
Continuity mistake: As Hawkeye writes a letter to his dad, he says "Christmas, here in Korea, as with you in Vermont, is soon upon us." Later, his dad is in Maine, and has lived there all his life.
Continuity mistake: In the Swamp, as Hawkeye asks about Peg's cookies, BJ folds the cards in his hand, and places his left hand over the top. In the close up, as he answers, he suddenly has the cards back in a fan.
Continuity mistake: As Rizzo turns to Potter to give the test score, he puts his cigar in his mouth, and his right hand on his papers. The next shot the cigar is suddenly in his right hand.
Father's Day - S9-E4
Continuity mistake: As Margaret sits on the bunk to talk with Al, his hands are by the table's edge. When the angle changes, they're up at chin level.
Continuity mistake: As Charles talks to the guys in the Swamp, his right hand alternates from up at his chest to down by his side several times too quickly to be normal.
Preventative Medicine - S7-E22
Continuity mistake: In the Mess Tent, as Lacey explains the reason he wants the hill to Margaret, he is holding a knife in his right hand. A second later, it's gone.
Peace on Us - S7-E2
Continuity mistake: As Hawkeye storms out of the Swamp, he leaves Charles, Potter, and BJ behind. After the angle changes, you can see there is nobody in the tent, and the still is missing.
Continuity mistake: When the Jeep runs over the French horn, the crowd is a good distance back. When Potter comes out and picks up the flattened horn, the crowd is only five or six feet away without having moved up.
Continuity mistake: As the discussion about Burns draws to a close, Potter starts to grab the files on his desk. As he says "Dismissed", he grabs them again.
Continuity mistake: From the back, Potter is facing directly at Hawkeye and BJ. From the front, he's in quarter profile, left side forward.
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.
