I'd say skip the harness if that's what they wish. . And the heck with rules and weight limits.  Let them do intuitive diving. And don't embarrass them about weight.  Or participate in any sort of training. Let them lay about the the lounge and eat Cheetos while the able bodied receive safety tips. After doing everything to cater to them the only rule would be that they must jump, or be pushed from the plane    Oh, and my company would be called, DDD. Deathfat Diving Disposal
