NEWS UPDATE: Germanwings plane crash: A320 Pilot Says Co-Pilot Can Be Locked Out Of Cockpit

Marignane, France: The co-pilot "voluntarily" initiated the descent of the Germanwings flight that crashed into the French Alps, the lead investigator says.
Andreas Lubitz, the 28-year-old co-pilot, also refused to open the door to the pilot who was outside the cockpit.
"The co-pilot is alone at the controls," prosecutor Brice Robin said on Thursday, recounting information gathered from the "black box" recorder.
"He voluntarily refused to open the door of the cockpit to the pilot and voluntarily began the descent of the plane."
