It's also important to try to avoid jumping to conclusions without the facts. If this is a new 737 and there's a manufacturing issue, then rake Boeing over the coals. They do have problems. But if this is an older plane that had either maintenance issues, then go after Southwest first unless it's a Boeing responsibility. And of course, things do happen beyond anyone's control too, and engines that fail for any reason but don't take out the rest of the aircraft is a bit of a win for design.
