My question was not looking for someone to blame for AF447, but trying to analyze the root causes of that crash as they would apply towards the future of aviation, that will have hundreds of passengers flying one-pilot, then no-pilot craft.
AF447 involved a plane that did not correctly represent it's state of having failed airspeed sensors followed by the deep stall to the pilots. The airline never trained it's pilots to recognize and address such a scenario, and the pilots never correctly deciphered the contradictory information at their disposal.
While blame can be attributed to the Airplane manufacturer, the airline, and the crew, blame should not be viewed as something to react against (unless you are a lawyer) as much as it should be freely discussed and used as a stepping stone to prepare for the future, which will undoubtedly see unmanned airliners giving us better reliability and cheaper flights.
