“Into distant time we travel, where a unique civilization has arisen . . .
“Our time explorer walks blithely through the air over the city of the future in which he has suddenly found himself. On his feet are shoes holding the small turbines that compress the air beneath him, thus giving him a cushion on which to walk.”
{1930's version of Marty McFly's hoverboard in "Back to the Future, Part II")
