Why the Final Moments Inside the Germanwings Cockpit Are Heard and Not Seen

 The co-pilot who intentionally crashed a Germanwings flight into a mountainside remained calm during the last 10 minutes of his life. French investigators have described the sound of even breathing on the cockpit audio preserved in the doomed flight's black-box recorder. Accounts of the crash invariably reconstruct those final moments: Andreas Lubitz, the 27-year-old first officer, alone on the flight deck; the captain locked outside, frantically banging on the fortified door as warning alarms sound. Lubitz doesn't speak a word before the deadly crash.
