Lebanon’s government has formally asked the U.S. based Odyssey Marine Explorations to send a submarine to help in retrieving the Ethiopian Airlines plane and the black box. Another ship for the company, Ocean Alert, has been scanning Lebanese waters since after the ET409 crash to try find the body of the plane and the black box.
The Boeing 737 crashed into the Mediterranean Sea on Jan. 25 just minutes after takeoff from Beirut in a fierce thunderstorm. All 90 people on board were presumed dead.
A U.S. Navy ship, the USS Ramage, has detected signals from the black box flight recorders at a depth of 4,265 feet (1,300 meters). Washington Post
