Air Berlin, Air France/KLM, and Lufthansa have sent aircraft through the cloud of volcanic ash that's crippled air travel for 4 days, and the head of KLM tells the BBC he wants to "get permission as soon as possible to partially restart our operations." The CEO of British Airways was a passenger on a test flight from Heathrow that landed in Cardiff, the Times of London reports. But the transport secretary, announcing the ban through 7pm tomorrow, said conditions would "not be safe for flights across most of northern Europe." The government is even considering using Royal Navy vessels to repatriate Britons stranded on the Continent. (More air travel stories.) Report an error
