Other: At the very beginning of the episode, when the men are riding over the English Channel, a man lights another man's cigarette, and the flame doesn't flicker. In a subsequent shot, it shows Winters in the doorway with the door open. If the door were open, the wind from the doorway would have made it impossible to light a cigarette. In the original book, Ambrose even remarks that the men were asked to choose between having the door open for fresh air, or closed so that they could smoke.
