Robotic Sub Set to Dive Again in Search for Missing Plane
A robotic submarine is set to resume its search for the missing Malaysian jet in the Indian Ocean one day after aborting its first mission.
The unmanned Bluefin-21 submarine was deployed on Monday night to start what was supposed to be a 16-hour search of the seabed for the Malaysia Airlines MH370.
But the mission was cut short after the submarine entered an area that exceeded its operating depth limit of 4,500 meters. U.S. navy officials say its built-in safety feature returned it to the surface and that it was not damaged.
Officials say data collected from the sub's six hour mission was analyzed and showed no sign of the missing plane.
The Joint Agency Coordination Center (JACC), which is coordinating the search, said the vehicle will be redeployed later Tuesday depending on weather conditions.
The submarine is being sent down nearly a week after sound locating equipment last heard signals that are believed to be from the missing jet's black boxes.
Locator beacons on the plane's flight recorder boxes emit signals so they can be more easily found, but their batteries only last about a month. It has been nearly 40 days since the jet went missing.
Biden to Speak at Boston Marathon Tribute
U.S. Vice President Joe Biden is joining local leaders in Boston on Tuesday for a ceremony marking the one-year anniversary of the deadly bombings at the Boston Marathon.
Biden is scheduled to speak at the event along with Boston Mayor Martin Walsh and Massachusetts Governor Deval Patrick. Organizers say the tribute will honor those affected by the bombing, and include victims' families and medical staff.
Two bombs exploded near the marathon finish line last year, killing three people and wounding more than 250 others.
Authorities say brothers Tamerlan and Dzhokhar Tsarnaev carried out the attack using homemade pressure cooker bombs.
The blasts set off a multi-day manhunt that ended with Tamerlan Tsarnaev dead from a shootout with police and a bloody Dzhokhar being arrested in a Boston suburb.
Dzhokhar is due to go on trial in November on 30 federal charges and will face the death penalty.
