Pilot miscommunication causes United flight to rapidly lose altitude before recovery

A United Airlines flight from Hawaii to California rapidly lost over 1,400 feet of altitude due to miscommunication between the pilots regarding flap settings.
The incident occurred shortly after takeoff when the co-pilot misheard the captain's instruction, leading to an incorrect flap configuration.
The pilots were alerted by the plane's warning system and able to recover control before any serious incident.
The NTSB investigation found the pilots failed to properly manage the flight path, airspeed, and pitch attitude.
United Airlines cooperated fully with the review and implemented changes to pilot training procedures.
