US air travel returns to normal after technology breakdown

U.S. air travel returned mostly to normal Thursday, a day after a computer system that sends safety information to pilots broke down and grounded traffic from coast to coast.

By early afternoon on the East Coast, about 100 flights had been canceled and 1,700 delayed — much lower figures than on Wednesday, when more than 1,300 flights were scrubbed and 11,000 delayed.

Attention turned to the federal agency whose technology failure inconvenienced millions of travelers.
