The U.S. has been working cooperatively with our Malaysian, Australian and international partners for more than 2 months in an effort to locate MH370.
Mike Dean's comments today were speculative and premature, as we continue to work with our partners to more thoroughly understand the data acquired by the Towed Pinger Locator.
