Volcanic ash from Iceland forces cancellation of flights, disrupts travel for thousands
LONDON -- A cloud of volcanic ash that wafted in from Iceland shut down airports across Northern Europe on Thursday, causing a ripple effect that is expected to snarl air traffic around the globe for days.
The paralysis that began in London and Paris soon spread to Hong Kong and Tokyo, to Nairobi and Buenos Aires, and to New York and both of the Washington area's international airports. It was, by all accounts, one of the most bizarre acts of nature ever to constrict world travel, and it grounded tens of thousands of passengers internationally.
Until the eruption, which began last month, Iceland's long volcanic history was little known beyond trivia games, but as that legacy surfaced Thursday, so did news that the last time the Eyjafjallajokull volcano exploded -- 187 years ago -- the eruptions went on for more than a year.
Officials were at a loss to predict how long it would take for the ash to dissipate or for flights to resume.
If the particle-laden cloud lingers through the weekend -- and there were predictions it would take two days to clear once the eruptions stop -- it could disrupt plans of President Obama and other world leaders to attend Sunday's state funeral for Polish President Lech Kaczynski, who died in a plane crash. Experts said that the weather radar on aircraft cannot detect the cloud of ash and that the particles could choke jet engines enough to shut them down.
Eurocontrol, the European aviation agency, anticipated that 50 percent of the flights between the continent and North America -- there are about 600 a day -- would be delayed or canceled Friday.
The impact was immediately felt in Washington's airports, with the cancellation Thursday of 26 flights bound for Europe from Dulles International and Baltimore-Washington International Marshall airports. The airlines said they tried to contact passengers, alerting them that, with flights probably canceled again Friday, there was no point in coming to the airport.
Many airlines were issuing waivers for travel to destinations affected by the clouds of volcanic ash. American Airlines, British Airways, Delta, Lufthansa, SAS, United Airlines and US Airways said travelers would be able to rebook without penalty or obtain refunds depending on the destination.
Some flights that had taken off for Europe on Thursday were routed back to the United States, said Federal Aviation Administration spokeswoman Laura Brown.
Although it stifled air travel, the cloud that hung over Europe was so high -- between 20,000 and 36,000 feet -- that it wasn't visible from the ground and health authorities said it posed no immediate danger.
The restriction of flights from Heathrow, which, with 1,200 flights carrying 180,000 passengers each day, is one of the world's busiest airports, will affect dozens of flights to and from the United States and other hubs around the world. British Airways said on its Web site that customers booked on a canceled flight could re-book or claim a full refund.
