A computer breakdown briefly disrupted all air traffic in France and caused a cascade of delayed flights in multiple countries on Sunday, the last day of European summer holidays.
A spokesman for French civil aviation authority DGAC said the cause of the morning breakdown was still being investigated, hundreds of flights were delayed at airports from Britain to Morocco and beyond. Hours after the problem with a French automatic flight plan system was fixed, schedules still lagged elsewhere.
The problem had “no impact on flight security” and was fixed before midday, allowing traffic to resume, the spokesman said. Under the authority’s rules, he wasn’t authorized to be publicly named.
But DGAC temporarily halted all air traffic under French control, which included planes flying over France. The directive covered planes going in and out of Paris from Charles de Gaulle, one of Europe’s busiest airports.
Passengers travelling from neighbouring countries such as Britain were particularly hard-hit as air traffic authorities struggled to re-direct flights through Europe’s crowded air space.
British Airways said in a statement: “We do expect disruption to some of our flights to France and Spain, as well as services flying over those countries.” It offered free ticket exchanges to anyone travelling to France, Spain, Italy or Portugal.
A Royal Air Maroc pilot described the breakdown as ‘exceptional’, as he waited to take off for Paris from the Moroccan city of Casablanca. After a confusing delay, his flight was then rerouted to Milan.
