A Little Chicken Soup Wouldn't Hurt - S5-E10
Continuity mistake: While Molly empties all the homemade food from her black bag onto Carter's desk and then the men eat, Molly's purse is either hanging from her left arm or it's gone, depending on the camera angles.
Factual error: In the initial opening credits, there's a statement that the flying battle scenes were flown by the Air Force. At the time of the events depicted there was only the Army Air Corps. 1947 was the beginning of the Air Force.
