Investigators in France are continuing to examine the black boxes of the Boeing 737 max jet that crashed in Ethiopia last weekend looking for clues to the accident.
With the Boeing jet grounded worldwide until a cause is found, aviation authorities are hoping the boxes reveal some strong leads.
The New York Times is reporting the captain of the doomed jetliner reported problems almost immediately after takeoff.
In what sources called a panicky voice, the pilot requested to return to the airport and was unable to control the plane as it violently rocked side-to-side by hundreds of feet.
The flight crashed five minutes after take-off Sunday, killing all 157 people on board.
