let's rule that out. i think everything i have heard is it is truly just an accident. china has these new rules for the south china sea. we have had planes shot down in that area of the world before. this could have been a plane that has been shot down because it was violating some chinese air space rule. it could have been hijacked and landed in pakistan. i have heard all of these different kinds of theories. that's why you really need to, one, not rule anything out. at the same time make certain that the search efforts are being coordinated with our intelligence communities and vice versa so we can find out what really took place. it is a huge coordination effort. on top of that, you have the malaysian government that is being kind of fickle at this point. >> michael brown, thanks so much. i appreciate it. >> we're back in a minute.
