ADDIS ABABA, Ethiopia — A preliminary review of the “black boxes” recovered from a jetliner that went down in Ethiopia found similarities between that crash and one involving the same Boeing model in Indonesia five months earlier, Ethiopia’s transport ministry said Sunday.

Although a spokesman for the ministry would not detail what the similarities were, the information from the black boxes, as the data and voice recorders are known, suggests that Ethiopian Airlines Flight 302 may have had problems similar to those of Lion Air Flight 610.

Both brand-new Boeing 737 Max 8s crashed shortly after takeoff — Lion Air in October and Ethiopian Airlines last week — following erratic ascents, killing everyone on board.

The disclosure by the transport ministry came as a procession of empty coffins made their way to a churchyard in Ethiopia. The crash of the jetliner was so violent that mourners were left with few remains to bury. One hundred and fifty-seven people were killed in the disaster. (The Lion Air crash killed 189.)
