Asiana Airlines Flight 214 crash

Pilot mismanagement and confusion caused Asiana Flight 214 to crash in San Francisco last year, U.S. accident investigators concluded Tuesday.

The National Transportation Safety Board said there was confusion over whether one of the airliner's key controls was maintaining speed.

The agency also cited the complexity of the Boeing 777's autothrottle and pilot training by the South Korea-based airline as contributing to the crash, which killed three passengers and injured more than 200.
