BERMAN: New information that concerns the crash of the Ethiopian Airlines flight and the grounding of the Boeing 737 Max 8 and Max 9. The pilot of that flight apparently knew he was in trouble almost immediately. "The New York Times" reports the pilot requested, and he had a panicked voice, to turn back to the airport just three minutes after takeoff because the plane was speeding up abnormally. Our Anna Stewart is live near Paris, where the black boxes are being analyzed. What have you learned, Anna.</s>ANNA STEWART, CNN REPORTER: Well, as you said there, "The New York Times" article, which attributes all this to a source who has reviewed the air traffic communications, says that shortly three minutes after takeoff, the captain spoke to air traffic control back in Addis Ababa saying brake, brake, request back to home, in a panicked voice. Air traffic controllers apparently tried to scramble to find a runway, but they lost communication with the plane. Now, the plane was seen observed to have oscillated hundreds of feet up and down. And if you compare that to the Lion Air crash from last year, obviously the same type of plane, it's got a similar altitude pattern. Are they linked? Why did they crash? We really don't know. But the secrets are here in the BEA behind me in Paris. This is the specialized unit, one of the only laboratories in the world that can analyze and interpret the data. The boxes arrived yesterday. Those are the flight data record and the recorder that records the cockpit voices. Those are crucial clues to determining what happened. How long will it take? Up to 30 days is usual for this sort of investigation for a preliminary report, maybe less time. It depends how damaged they. As you can see from pictures, they look fairly damaged, but you really can't tell from the outside what it will be inside.</s>CAMEROTA: Thank you very much for that chilling update. Hearing the pilot's final words was -- is so alarming. Obviously, investigators are looking into that. We want to get back to our top story, and that's at least 49 people have been killed in this terror attack in New Zealand. So we have the latest details that are just coming into CNN, next.
Ethiopian Airlines Pilot Faced Emergency Almost Immediately.
