The US National Transportation Safety Board is sending a team of investigators to assist the government of Indonesia in the investigation of Saturday’s Lion Air Boeing 737-800 crash. The aircraft crashed on approach to Denpasar-Ngurah Rai Bali International Airport in Indonesia and landed in shallow water, injuring 45 of the 108 people onboard. There were no fatalities.

On Monday, Transport Minister Evert Erenst Mangindaan said the aircraft’s cockpit voice recorder has been found and is being retrieved, according to Bloomberg.
