i would love to see how someone "rappels out". That is pretty much an oxymoron unless you are rappelling out and down. The high-tech angle also seem media-hype to me. saws-all cuts hole, anchor ropes, rapel to top of shelf-rack and start sending up the booty, then ascend using either 1) a set of gibbs, 2) a 12-volt winch, 3) some buddies on steroids who don't mind hefting your 140 pounds 30 feet back to the hole. This is NOT "mission" anything in my book. give me and a few fairly rope-Able friends a couple beers and we'd come up the same plan. Their main reason for success was scoping out security beforehand (poss'by with inside help).
