So it was the fault of the co-pilot? The BBC website reports:
The co-pilot of the Germanwings flight that crashed in the French Alps, named as Andreas Lubitz, appeared to want to "destroy the plane", officials said.
Marseille prosecutor Brice Robin, citing information from the "black box" voice recorder, said the co-pilot was alone in the cockpit.
He intentionally started a descent while the pilot was locked out.
There is something disturbing about the way the authorities rush to blame human beings for aeroplane crashes, conveniently letting the airlines and the aeroplane manufacturers off the hook. In this case, I have no grounds to dispute the initial findings but I am minded to suspend judgment until the investigations are concluded.
