Passage:On 17 April 2010, the president of German airline Air Berlin, in an interview with the newspaper Bild am Sonntag, stated that the risks for flights due to this volcanic haze were nonexistent, because the assessment was based only on a computer simulation produced by the VAAC. He went on to claim that the Luftfahrt-Bundesamt closed German airspace without checking the accuracy of these simulations. Spokesmen for Lufthansa and KLM stated that during their test flights, required by the European Union, there were no problems with the aircraft. On the morning of 17 April Lufthansa moved 10 aircraft from Munich to Frankfurt at low altitude following visual flight rules. There were no problems reported and no sign of damage to the planes. The same day, an Airbus belonging to Ural Airlines attempted flying below the ash clouds from Moscow to Rimini.
