Investigators have retrieved cockpit voice recordings from one of the black boxes of the German Airbus plane that crashed into the Alps, killing everyone onboard, officials said on Wednesday.
The New York Times reported that evidence from the recordings showed that one of the pilots left the cockpit and could not get back in before the flight went down.
"The guy outside is knocking lightly on the door and there is no answer," an unnamed investigator told the Times, citing the recordings. "And then he hits the door stronger and no answer. There is never an answer."
