Character mistake: As Potter and Hawkeye pull up to the MP checkpoint, Potter and the MP exchange salutes. As per Army regulations, no salutes are given under battle conditions. The reason is that if the superior officer, in this case Colonel Potter, returns the salute, he can be a target for snipers.
Dear Sigmund - S5-E7
Continuity mistake: As Frank talks with Sidney, hiss right wrist is beside his knee. A second later, his right fist is on his leg.
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.
Other mistake: Looking at the pins when Margaret bowls at the end, the 5 pin slides backwards towards the camera, but not fast enough to bounce off anything and then fly in from off screen. Granted this was done in slow motion, but the physics don't seem to add up.
'Twas the Day After Christmas - S10-E9
Continuity mistake: As Potters is talking to Winchester, he's pointing at Charles to emphasize his point. As the angle changes, his hand is suddenly lowered, and he points to the cook.
Give 'Em Hell, Hawkeye - S10-E4
Continuity mistake: After announcing that the visiting Colonel likes the project, Potter's left arm is at his side. A second later in the close up, it's behind his back.
Continuity mistake: As Potter pours the drinks for himself and Brandy, the glasses have enough for a sip. In the close up, they're a quarter to half full.
Continuity mistake: In Potter's tent, he holds the door for Brandy to enter. In the close up, you see him drop his left hand to close the door after she passes him and inside. After the angle change, his hand is back on the door, and she's just even with him walking forward.
Continuity mistake: As Klinger and Margaret are talking about the date, he takes a sip of his drink and goes to put his hand down. After the angle changes and he goes to say his line, he repeats putting the glass down.
The Merchant of Korea - S6-E14
Continuity mistake: After answering a call for help, BJ gets first a right glove on, then as he talks, gets a left glove. After the angle changes, he gets a left glove again.
Continuity mistake: In the last O.R. of the episode, Winchester is wearing a surgical gown with the same blood stain pattern as in the previous episode. This also would be impossible given the cleaning procedures.
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.
Continuity mistake: As Henry watches the chopper fly off, his back is to Radar's jeep. After he orders back to camp, Henry is suddenly standing with his right side to the jeep without having turned.
Continuity mistake: The syringe the "Mad Turk" threatens Henry with alternates between fully ready to almost empty between shots.
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: As Radar is sorting mail, and Trapper makes a joke, Radar starts to put a letter down. After the angle change, he puts the letter down again.
Deal Me Out - S2-E13
Visible crew/equipment: After the C.I.D. man comes into the swamp and makes reference to Klinger, who looks up, you can see a studio light panel reflected in his shades.
Continuity mistake: As the boys talk to Col. Lambert, Trapper is back a bit from the table. When the angle changes, he's a lot closer.
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.
