San Francisco, California -
(NBC News) National Transportation Safety Board investigators say it was pilot error that led to the deadly Asiana airlines crash last year.
During a public hearing, Tuesday NTSB officials repeatedly referred to the pilot's lack of understanding and "misconceptions" about the autopilot systems on the Boeing 777 as Flight 214 approached San Francisco International Airport.
"This was a seasoned flight crew with a good safety record, yet they misunderstood the relationships of the automated systems that they commanded," said NTSB Acting Chairman Christopher Hart. "They also failed to work together to monitor and respond to their deteriorating situation."
Three people died and more than 180 were injured in the crash, but and not all of the problems were in the air.
Two passengers not wearing seat belts were ejected from the plane on impact and one died after being run over by two fire trucks responding to the accident.
