Failures in a computer system in California grounded hundreds of flights at US West Coast airports Thursday, bringing chaos to airlines and long delays for passengers.

Flights elsewhere in the US were also affected when Federal Aviation Administration officials ordered a short "national ground stoppage."

According to the FAA the problems were caused when an overnight upgrade of computers went wrong and affected radar information.
