Name That Trauma :: Brad R. On Space Vent Stuffed With Meat

Hello there, long-time reader here.

Perhaps the readers can help me with this; unfortunately 20+ years have left me wondering how much of this actually happened in what I saw and how much was assumption on my part.

Sometime in the late '80s I walked into the rec room while my father was watching something on TV. I believe the scene involved a group of people that survived a crash in some form of space ship, though it could have easily been a plane. One of the group convinces the others to leave the ship/plane and explore. The next thing that I remember is one of the group, having stayed behind, is crouching down or sitting near some sort of vent or other slim opening and sees what looks like sliced or ground-up meat coming through. He freaks out as he thinks that it is one of the other group members having been murdered or otherwise killed in gruesome fashion. I think the film heavily implied or flat out showed that he was wrong and that whatever was coming through the vent was not the result of someone's gruesome death. It's possible that I decided that on my own, though, I can't remember. I do have this image in my head of someone standing on the other side and may have intentionally been pranking the guy into thinking someone had died by stuffing something through that vent.

Not really a traumatic memory, but it was somewhat unsettling at the time. Does this sound familiar?
