up and down, so the navy has this special system that that line is routed around a pulley on top of basically a big shock absorber. so there is no snap load on the line. and again, they have a lot of experience doing that. it is just a matter of timing. i believe that fadoss system is out there, i believe the navy vehicle again, other vehicles can work at depths. the underwater vehicles are designed do certain things. let me ask you this other people s rovs may not be designed do that sort of thing. you say they have done that with the f-35 and the helicopter, but those did not have living human beings on them. has anyone ever successfully recovered people from depths this far down? i don t believe from depth.
