Yes, that does ring a bell. I saw that one also and I've obviously confused parts of several together over the years. There's definitely another film in which the pilot played by Richard lost his dinghy. As he looked down and watched it fall away he silently mouthed the time honoured, one-word oath often heard in such a situation. The last scene is him being picked up by a SAR vessel or helicopter or something but after he succumbed to the cold.
