The Other 48 Hours

Back when I was in first grade, there was a really creepy (at least to a six year old) film short about aliens. I remember that my class really liked that one. This was back in 1981, so it was played on an old reel to reel projector. If I'm not mistaken, it was titled "48 Hours". Does anyone else remember this?
