Visible crew/equipment: As the car with the kidnapped Klink takes off, the Stalag 13 buildings are reflected in the windows, along with the camera equipment and lighting. (00:01:20)
Will the Blue Baron Strike Again? - S4-E12
Continuity mistake: The cigar Hogan takes from Klink goes from green to light brown when starts to name the top invitees to the party.
Continuity mistake: As the ambulance leaves the hotel, there is snow on top of the fenders and spare tire. Back at the truck, there is snow on the fenders, but not the spare. This would be impossible as at the speed driven, the snow would have blown off any horizontal surface.
Continuity mistake: As Hogan, Carter, and Newkirk go to get out of the Army truck, the ambulance doors are wide open. As Hogan walks by, the doors are straight out toward the truck.
Other mistake: As Schultz goes to stick a pin in the map, he supposedly hits his finger. But if you look closely, he actually stuck it in the map at the very tip of his finger. This is clear because he didn't move the pin at all.
Continuity mistake: In this episode, the Notausgang (Emergency Exit) sign is over the door. In other episodes, it is on the door.
Continuity mistake: The bridge Buckles and the boys put TNT on is significantly different than the one blown up. Also, the one destroyed is a re-used shot of a bridge being blown up.
Other mistake: As Buckles holds up the scale model of the Bismarck, the diagonal cut where it's supposed to "break" is visible.
Continuity mistake: The apple that Freddie is eating at the end goes from green to red.
Continuity mistake: When Hogan is by the truck, Newkirk responds to his question about packages. Crittendon has his swagger stick under his arm, then it's suddenly in front if him in his hands.
Is There a Doctor in the House? - S3-E18
Other mistake: As Carter gets ready to clean out the stove, Newkirk closes his eyes and winces just before the bellows Carter has blows.
An Evening of Generals - S3-E13
Continuity mistake: In Klink's office, the lower corner of the poster Hogan holds up alternates between being over the right side of his chest, to being tucked under, and back.
An Evening of Generals - S3-E13
Continuity mistake: In the barracks, after Hogan asks Newkirk about volunteering, the coffee cup Newkirk has is held with his left hand fingers in the handle. After the angle cut, the cup is in his hand with the handle toward the camera.
Clearance Sale at the Black Market - S4-E1
Revealing mistake: After Kiegel shoots out the bulb the light takes a couple of extra seconds to fade out.
Visible crew/equipment: As Klink's car pulls up, and Klink comes around the front of it, the shadow of the camera is visible.
Nights in Shining Armor - S3-E8
Other mistake: When Hogan shoots the vest, it stays still for a couple of seconds then swings in a way that is not normal.
The Safecracker Suite - S1-E27
Continuity mistake: After saying "I hate to be a killjoy", Newkirk has his fork up and pointed towards Kinchloe. A second later, it's pointed down.
Factual error: Numerous times throughout the series, there are palm trees seen in different shots. Stalag 13 was supposed to be just on the outskirts of Hammelburg. The only place anywhere near there that could support palms was the area around the Bodensee (Lake Constance), so therefore the palms seen are a big mistake.
Anchors Aweigh, Men of Stalag 13 - S1-E16
Audio problem: As the last German soldier before Hogan goes up the ramp, Le Beau is heard saying "schnell, schnell!" (fast, fast). As he says it, his mouth doesn't move.
