Air traffic problem at Schiphol causes delays, cancellations

Dozens of flights to and from Amsterdam's busy Schiphol Airport were delayed or cancelled Tuesday because of a technical problem with air traffic control systems.

Schiphol said that the problem was resolved by late afternoon, but passengers could still face delays into the evening.

KLM, in a tweet, called the problem a "major disruption" and said it cancelled 25 European return flights.

Air Traffic Control the Netherlands said in a statement shortly before 5 p.m. (1600 GMT; 11 a.m. EST) that its systems had been successfully restarted but added that it would take time before the system was working at full capacity again.
