Blue sky, no clouds, mid afternoon. I heard jet engines so I looked up. It was a 737. I saw it and the contrail that dissipated seconds after it left the engines. Suddenly the plane disappeared. It was as if a giant invisible eraser traveling in the opposite direction erased it from the sky. I kept looking for it but it was gone. No plane. No contrail. No sound. Did it glitch out of this reality? Did it enter a portal? Don't know what happened.
