Some people, planes, ships and objects make contact with shifting portals in time and space and end up... well, nobody knows. But sometimes we find working wristwatches in ancient, unsealed Egyptian crypts, or see them in vintage photographs. Time and space has burps and hickups, eddies and rivers, ripples and overlapping waves, and sometimes things get caught in them and are taken elsewhere or elsewhen. They may not even end up in this universe.
