Madrid, Rajab 20, 1436, May 9, 2015, SPA -- An Airbus military transport plane crashed while performing a test flight in Spain on Saturday, killing four crew members, officials said. According to dpa, Spanish emergency services said two crew members were in hospital with serious injuries while at least one other was missing. Prime Minister Mariano Rajoy said earlier that between eight and 10 people were on the Airbus A400M when it went down shortly after takeoff from Seville Airport in southern Spain. All crew members on the flight were Spanish citizens, Rajoy said, adding that they were likely all employees of Airbus. The cause of the crash was unclear. The Ministry of Transport said it had launched an investigation. The Airbus A400M is assembled in Seville and is undergoing flight trials. The crashed aircraft was destined for Turkey, Airbus said in a statement. --SPA 19:20 LOCAL TIME 16:20 GMT www.spa.gov.sa/w
