The investigation into the crash, which killed all 189 people on board in October, has taken on new relevance as the US Federal Aviation Administration and other regulators grounded the model last week after a second deadly accident in Ethiopia.
Ethiopia's transport minister Dagmawit Moges says analysis of data from Boeing 737 MAX 8 black boxes show 'clear similarities' with October's Lion Air crash. Meanwhile, funerals were held for Ethiopia crash victims with little to bury.
The list of countries grounding or denying airspace to the Boeing 737 MAX series of aircraft is growing, after a second deadly crash of the MAX 8 on Sunday when an Ethiopian Airlines flight crashed soon after takeoff killing all 157 people on board.
