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: In some shots the Spam lamb has mashed potato eyes and a carrot mouth, in others it has green grape eyes and no obvious mouth, and it keeps changing. (00:23:10)
Continuity mistake: In the shot where Hawkeye presents the Spam lamb to Henry, he sets it down, and Henry asks him what it is. Behind Henry, you can see Hawkeye's shadow - and see his lips mouth the word "A Spam lamb". The camera then changes to a close-up of Hawkeye, saying "A Spam lamb".
Continuity mistake: When Radar goes to get the lamb, he pulls out a hypo to put the lamb to sleep for shipping. When the shot cuts to the lamb, you can see both of Radar's hands on the lamb's face; no hypo in sight.

Continuity mistake: When Henry, Trapper, and Hawkeye get into the jeep with Radar notice the style of jeep and its number is 16930382, but when they're driving to the chopper pad the style differs - things such as hood, antenna, etc, and its number is 11172419. Then when the chopper takes off the jeep's style is back to the original jeep they were in.
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: Just after the announcement that General MacArthur is coming, Trapper puts on his sunglasses, then the shot switches to Henry walking, and in the background Trapper is putting his glasses on again.
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.
