German air controllers fix problems after travel disruption warning

German air traffic controllers have fixed technical problems which had disrupted European travel on Wednesday, air traffic control firm DFS said. "From 9 a.m., we will resume work with 100% of air traffic," said a spokesperson for DFS, whose controllers monitor take-offs and landings at 15 international airports in Germany. The problems, which started around 3 a.m. local time (0100 GMT), were caused by an unexpected issue during a software update overnight, which forced DFS to limit air traffic to 50% of normal capacity Pan-European air traffic agency Eurocontrol said on its website that there were moderate to high delays in many parts of German airspace on Wednesday, citing issues including computer problems with air traffic control equipment, staffing and the Ukraine crisis. Frankfurt airport, one of Europe's busiest and a hub of flagship carrier Lufthansa, was affected in particular.<br/>
