Europe

Up to half of flights delayed

European air travelers faced mass disruption on Tuesday, with up to half of all flights delayed after the system that manages air traffic for the continent broke down. Nearly 15,000 flights could be held up by the problem, according to Eurocontrol, the Brussels-based agency in charge of managing Europe's skies. Several of the EU's biggest airports, including Amsterdam's Schiphol, warned of problems and advised passengers to check on their flights because of the computer breakdown.
