I've occasionally wondered about the depth of training the pilot of an aircraft that I was riding had had. At least I live to wonder.
An Airbus 330 on Air France Flight 447?
"But neither Bonin nor Roberts has ever received training in how to deal with an unreliable airspeed indicator at cruise altitude, or in flying the airplane by hand under such conditions."
Take a wild guess what happens next.
There were 228 souls on board.
