When lifting the unconscious soldier out of the tub, his head is away from the camera (pointed toward the wall), but when he'd placed on the table, he is reversed.
At the end, everyone is hovered around the soup, waiting to get some. Margaret is also waiting, and is close to the soup. The camera changes to see Margaret sitting at a table with an empty cup. Charles sits next to her and gives her one of the two cups he has so she won't have to wait in line.
As stated, the temperature at the 4077 is 13' F (-10'C), however, visible breath never comes from the characters. This is because the series was filmed in Los Angeles, California, and Malibu State Park,
California, where the ambient temperature was not truly cold enough. Smoke can be made to come off fire bins but not out of the actors. -One's breath is visible in colder temperatures due to relative humidity and dew points, not the temperature itself.
Loretta Swit's fingernails are over an inch long. No nurse, especially a head nurse, would have fingernails that long.
Hawkeye orders a nurse to put a tube down a patient's throat and use warm D and W to warm the patient.
Normally, this process is used as a gastric lavage (normally used to wash poison out of the stomach or check stomach contents for blood) and is done with a 0.9% saline solution (known as normal saline solution). The solution Hawkeye refers to is not that; it's referred to as D5W, which stands for Dextrose 5% in water, and is not traditionally used for lavage. However, Hawkeye is using the warm solution to warm the patient, and he may want the benefit of the calories found in the dextrose.
The episode is supposed to take place in the dead of winter, however, leaves are clearly visible on trees in exterior shots and the actor's breath is noticeably absent.- One's breath is visible in colder temperatures due to relative humidity and dew points, not the temperature itself.
Colonel Potter says he'll never get to see the end of "Sun Valley Serenade" due to an emergency. All he had to do was rewind the film and watch it again.
Several times during the series, a doctor requests an "Ambu-bag" (a brand of resuscitation breathing masks). "Ambu" brand resuscitation masks did not exist before 1953.
You hear a howling wind in numerous interior and exterior shots to emphasize the frigid wind-chill-induced temperatures. However, tents aren't flapping, smoke from the chimneys is rising vertically, doors being opened aren't affected, and hair, blankets, and clothing being worn aren't moving.
While watching the Sonja Henie movie Sun Valley Serenade (1941), Colonel Potter says at one point of the movie, "This is supposed to be where she does a triple axel and ends up in a split." Then he has to leave and says, "Now I'll never get to see it." Midori Ito from Japan was the first woman to complete a triple axel in competition in 1989, and Tonya Harding was the 2nd woman to complete one and the only American woman. It is unlikely Sonja Henie ever did anything as complicated as a triple axel even with her three Olympic Gold Medals. More to the point, the action he describes does not happen in her performance in the film.
