The investigation continues as to why a Germanwings flight from Barcelona to Düsseldorf crashed in the French Alps.
FOX News Radio's Simon Owen reports:
The CEO of Germanwings -- the airline operating the flight saying two Americans were among the 150 people on board. All are feared dead. The head of Germanwings' parent airline, Lufthansa, saying the plane was in perfect condition. He calls the crash inexplicable.
Rescue workers are back on the mountainside, picking through the wreckage.
Investigators have retrieved the plane's cockpit voice recorder -- as they try and discover why no mayday call was made, as the plane made an eight-minute descent before crashing.
