Bodykiting

From the tail ramp of a suitable aircraft, you´re winched out on a 50-100m line attached to your harness. The attachment point needs to be somewhere near your belly button.

As long as the aircraft is doing a reasonable speed (I´m guessing 200mph), you ought to become a sort of glorified kite, capable of soaring and swooping on the line. It would be radically different from freefall, but would use a lot of the same principals for control. You would have freedom of movement within a large arc either side of, and above and below, the aircraft (though your distance from the plane would remain constant).

Experienced bodykiters ought to be able to fly in pairs or more, performing a sort of glorified horizontal high-speed maypole dance. It may even be possible to do human kite-fighting (with ground-glass covered lines), though I´m not sure how. Or why.

Possible risks include strangulation (íf a deft maneuver managed to loop the line around your neck; this would be tricky, though, as it would be under considerable tension) or terminal plaiting (amongst groups of three or more bodykiters).

After bodykiting, the kiter would release the line, and start a regular skydive; or they could be winched back in.
