Quote:A lift-capable vehicle like a glider is inherently safer, because you have more control over the descent stage.Two big problems with gliders (they need atmosphere, and they need a smooth landing strip) mean they can only be used for the return to Earth, not setting down on another planet, so we'll still need to develop/improve rocket-descent vehicles if we want to put people on just about any other world.
