The Coast Guard's First District reported early Wednesday that a Canadian P-3 aircraft detected underwater noises in the area where crews are looking for the missing Titan submersible and operations were redirected there. Those efforts "have yielded negative results but continue," the Coast Guard tweeted.
Crews are searching a massive swath of sea about 900 miles east of Boston, with time running out on the oxygen supply aboard the missing submersible that was set for the ocean floor wreckage of the Titanic.
