(Reuters) Airlines rushed on Thursday to change rules to require a second crew member in the cockpit at all times, hours after French prosecutors suggested a co-pilot who barricaded himself alone at the controls of a jetliner had crashed it on purpose.
The United States already requires two crew members to be in the cabin at all times, but many other countries do not, allowing pilots to leave the flight deck, for example to use the toilet, as long as one pilot is at the controls.
That is precisely what French prosecutors suspect happened on the Germanwings flight on Tuesday. They sayAndreas Lubitz, 27, locked the captain out and appears to have set the controls to crash into a mountain, killing all 150 people on board.
