The Airplane

This happened a few months ago, but the more I think about it, the more it creeps me out.

I was walking my normal route to school when I noticed an airplane in the sky. This airplane was pretty close to land (as it seemed big in the sky) yet it was moving really slowly. In fact, it seemed to be moving too slowly for a plane that close to earth, and I almost expected it to crash down. Anyway I tried to shrug it off, though no more than a minute later I had turned the corner, looked up at the sky again, and it had gone. Completely vanished. And I can tell you that at the speed the plane was moving, there was no way it would've moved out of my sight just by turning the corner.

I still don't know what happened, and I have never seen a plane in that area ever since.
