Britain has temporarily suspended military flight training on Eurofighter Typhoon jets after inspectors found deposits of ash in an engine of a fleet plane, dpa quoted the Ministry of Defence as saying today. The announcement came two days after new EU guidelines were agreed for safe levels of volcanic ash in the atmosphere, leading to the reopening of airspace across Europe. The ministry said Royal Airforce safety inspectors had taken the "precautionary measure" to check all of the jets based at RAF Coningsby, in Lincolnshire, eastern Britain, after finding small deposits Wednesday. "These are very high performance jets so they are just being extra cautious," the ministry said. The Typhoon, known as Eurofighter in other European countries, is a multi-role combat aircraft developed jointly by Britain, Germany, Italy and Spain.
