Corrected entry: When LeBeau goes to get out under the wire, he raises an entire section of the wire on the inner and outer fences to do so. It can be seen that there is a bar on the bottom of the sections that he raises that suggests the sections are totally framed for the purpose.
Corrected entry: In the very beginning, the prisoners are all in formation for a count. Shultz completes the count at 15, reports it, and Klink calls Hogan over to talk. This leaves 14 in formation. Hogan says "Smoke if you have them". Unbeknownst to Klink, the men are in an arrow formation to point the way to the bridge for the bombers. The aerial shot from the planes shows at least 25 lighters lit. Where did the other 11 guys come from? With Hogan, his barracks only had 15 men who would've been in on it.
Corrected entry: On the cover of the plan for Operation Hannibal, the top line says. "SEHR GEHEIM" (Top Secret). But the plan is called Operation Hannibal (translated as "betrieb hannibal"). The title says "unternehmen hannibal (translation: Companies Hannibal).
Corrected entry: The whole story line is a plot hole. The blueprints would be a top secret item, and as such, wouldn't accompany the item they depict (in this case, missiles). Klink carries the prints around as if they were ordinary papers for no other purpose than to be "borrowed", copied, and returned by the Heroes. For this, Klink would have been eliminated.
Corrected entry: As the scene fades to the Höf Brau (with lighting that would violate black out rules in wartime Germany) passing vehicles can be seen to be modern (mid-1960's) cars rather than the more appropriate early 1940's German vehicles. And they're travelling at 1960's standards speeds.
Corrected entry: When Hogan goes to shake hands with Baumann, he grabs and raises Baumann's arm to make the wrist gun fire upwards. As it fires, it takes Klink's hat off. Upon inspection, Klink's hat has only one hole, as if fired through from underneath. The gun fired at the peak of the hat, therefore, there should be a second hole about the level of the top of the eagle on the front of the hat.
Corrected entry: When the Inspector General walks toward Klink's office, he falls into a fake tunnel section. As he goes down, he has his outer coat over his shoulders. When the shot cuts to him in the hole, the coat is missing without having fallen off. After he is out, the coat is returned.
