WASHINGTON (AP) - A cascading computer failure in the nation's air-traffic control system caused severe flight delays and some cancellations Friday along the East Coast.
A computer system in Atlanta that processes pilots' flights plans and sends them to air-traffic controllers failed early Friday, Federal Aviation Administration spokeswoman Diane Spitaliere said. In response, the agency rerouted the system's functions to another computer in Salt Lake City, which overloaded because of the increased volume of data, magnifying the problem.
The FAA could not immediately calculate the number of flight delays caused by the problem, which was made worse by bad weather, Spitaliere said. Airlines experienced thousands of delays, some lasting several hours, in what was shaping up to be one of the country's worst days this year for air travel.
