Spain withdraws permission for Airbus A-400M test flights

"It's obvious that, to be careful and until we know the result of the investigation, it doesn't make sense for planes currently in the production phase and going through tests, to be able to fly without knowing what really happened to the plane," Morenes said in an interview with Spanish radio Onda Cero.

Four crew were killed in the accident during testing outside Seville, Spain, which prompted Britain, Germany, Malaysia and Turkey to ground their fleets of Europe's new troop and cargo carrier.
