ADDIS ABABA, Ethiopia — A jetliner with passengers from at least 35 countries crashed Sunday shortly after leaving Ethiopia’s capital, killing all 157 people on board and renewing concerns about the new model of aircraft involved in the accident, the popular Boeing 737 Max 8.

After taking off from Addis Ababa in good weather and with clear visibility, Ethiopian Airlines Flight 302, bound for Nairobi, Kenya, struggled to ascend at a stable speed, according to flight data published by FlightRadar24. The pilot sent out a distress call and was cleared to return to the airport, Bole International, the airline’s chief executive told reporters.

But the plane — the same Boeing model that went down in Indonesia in October, killing all 189 people on board — lost contact with air traffic controllers six minutes after takeoff. It then plummeted to the ground near Bishoftu, a town southeast of the capital.

“At this stage, we cannot rule out anything,” the airline’s chief executive, Tewolde GebreMariam, told reporters.

Images from the vast, smoky crater at the crash site revealed a grim tableau. Workers loaded black body bags into a truck, while plane fragments and various items from the flight — cigarettes, shoes, napkins with the Ethiopian Airlines logo — were strewn across the field.
