A propeller is mounted within a shroud to produce an upwardly moving air flow to levitate human beings. The user wears an air inflatable suit and a harness. A couch is disposed just outside the shroud to support the user in prone position. A jib crane is positioned near the couch and shroud and carries a self-winding reel to which a strap is attached at one end, the other end of the strap carrying a hook which is attached to the harness at the back of the user. The jib crane lifts the user off the support through the strap and translates the same above the shroud within the air flow being suspended by the strap in prone position. When the user is levitated by the air flow, the reel automatically reels in the strap.
