I don't believe the intention of that test was to try and safely put a plane down in a desert. It was a remote controlled crash test. The wiki page[1] says the descent rate was 1500 feet per minute. A typical touchdown rate according to the linked MIT article about this crash[2] puts airliner landings at 10-20 feet per minute.

So if this ever happens to a plane you're on, it's the rich guys in first and business that will cop it. Economy will probably survive.

Nice reversal of the way things normally happen!
