A Klink, a Bomb and a Short Fuse - S2-E8
Continuity mistake: Klink comes out to demand his code book be returned. In the wide shot, Hogan has a book in his right hand. In the close up, when he points at Klink with his right hand, the book is gone, and back in the wide shot.
A Klink, a Bomb and a Short Fuse - S2-E8
Continuity mistake: The lapels of Schultz's jacket have yellow rectangles where the insignia of rank are. Normally, he has four eagles on them meaning senior Sergeant. In the close ups close to the end, the top piece is missing on the right lapel.
A Klink, a Bomb and a Short Fuse - S2-E8
Other mistake: After Burkhalter gives Klink the order to help disarm the bomb, the camera cuts to Hogan and Klink. Between them and over the barracks, you can see the Desilu water tower.
A Klink, a Bomb and a Short Fuse - S2-E8
Continuity mistake: When Burkhalter is standing with Klink after he first arrives, Burkhalter's arms are by his side. When the camera cuts to a close-up, Burkhalter's arms are crossed behind his back, much too quickly than is possible.
Plot hole: The boys take out the radio control unit from the mini tank. Le Beau is needed to get in and drive it to make it appear okay. After going between the buildings, they get him out, and start it on its way. Trouble is, no remote control and no driver, yet it turns and operates smoothly.
Audio problem: As the baby tank runs by the group in a wide shot, you see Hogan's mouth moving in a conversation, but the words don't match up.
Revealing mistake: As Hogan goes through the hole to the ladder, the "rock" he brushes against flexes for a second. Likewise, when Kinch climbs through, the "rock" under his hand flexes and mashes down as his weight is on it.
Factual error: In the very end, Klink comes up to the boys. As he stands beside Hogan, the Desilu Studios Water Tower is present behind them.
Don't Forget to Write - S2-E13
Other mistake: When the recruiting officer is talking to Klink, Hogan and company listen in, as usual. The problem is the coffee pot. Any other time, they take off the top, take out the basket (which is the speaker) and plug in the power: this time, they forgot to remove the top to hear it, which would have muffled the sound. But the conversation was heard just the same.
Continuity mistake: After Hogan leaves the airman in the tree, LeBeau jumps down, and looks up to tell the man it will be OK. When the camera looks at the man, you see LeBeau's legs and feet behind him.
Visible crew/equipment: As the General gets in his staff car and it leaves, the film crew and equipment are reflected on the sides.
Audio problem: The top of the coffee pot is on the basket rather than open, but we can hear the conversation.
Continuity mistake: As the general comes into Klink's office, Carter pours another cup of coffee, and starts to put the pot down. A second later, he's putting it down again.
Continuity mistake: During Carter's second meal, the napkin in his shirt comes loose and starts to fall. A second later, it's firmly in place in his shirt.
Factual error: The German agent pretending to be an American pilot is wearing a one piece flying suit from the 1960's when he is questioned by Hogan and the British escapee in the barracks. It even has the US Air Force logo on the sleeve, which didn't come into use until 1947, after the war.
Revealing mistake: When Schultz checks the barbed wire to see if it is fixed now, he noticeably wiggles the vertical wire, but only barely touches the horizontal one - because it is rigged to come apart, and will again if he handles it too roughly.
Other mistake: When the boys are listening to Klink's office, the lid is on the speaker instead of being off.
Continuity mistake: When Newkirk brings his hat loaded with candy, he hands it to Hogan with the badge on the top on Hogan's left. When the camera angle changes, the hat has been reversed.
Revealing mistake: When the boys are working on the fence, when the camera is on Hogan, you can see a modern metal building in the distance.
