Some guy in Canada has proposed a scheme to break a commercial airliner into component parts in an emergency. The separate sections would, if the theory holds, then descend to safe landings by way of "shock absorbers, parachutes and reaction jets." While the use of ballistic rocket-launched parachutes has been proven in light GA planes. I don't see this working on any sort of commercial bird. Too heavy and a maintenance nightmare. Just think of the consequences of a partial deployment either by accident or during a real emergency. This will never fly.
