Just my suggestion, for what it's worth.
After you find a suitable landing site, (I would suggest a long flat one with fire cover available), get the aircraft on the wrong side of the drag curve to start a rate of descent. As you get close to the ground the ground cushion should slow the rate of descent, if it's to high I suppose you could always try a little forward speed (but not above translational lift). If the aircraft sits on the ground cushion, gentle close throttle and overpitch onto the ground, should the aircraft run on, close the throttle(s) slowly or you will probably roll over.
Simple or what? It may sound simple, but I can assure you that this situation is a real nasty. Let's hope it never happens to you. Fly safely,
