ADDIS ABABA, Ethiopia (AP) The pilot of the Ethiopian Airlines plane that crashed requested permission "in a panicky voice" to return to the airport shortly after takeoff, The New York Times reports.
Friday's report cites "a person who reviewed air traffic communications" from Sunday's flight saying controllers noticed the plane was moving up and down by hundreds of feet, with its speed appearing unusually fast.
An airline spokesman has said the pilot was given permission to return. But the plane crashed minutes later outside Addis Ababa, killing all 157 on board.
French authorities now have the plane's flight data and voice recorders for analysis.
In Ethiopia, officials have started taking DNA samples from victims' family members to assist in identifying remains.
Countries including the United States have grounded the Boeing 737 Max 8.
