Germanwings A320 crash: Lufthansa boss 'very, very sorry'
Lufthansa's chief executive has said it will take a "long, long time" to understand what led to the Germanwings aircraft crash last week, which killed 150 people.
Carsten Spohr refused to comment on the mental health of the co-pilot, who is alleged to have deliberately flown the plane into the French Alps.
Meanwhile, a German newspaper and a French magazine say they've obtained mobile phone footage showing the last moments inside the aircraft before it crashed.
