Volcanic Ash Halts Much of N.Europe Air Travel..

A huge ash cloud from an Icelandic volcano caused further air travel chaos across Europe on Friday on a scale not seen since the Sept. 11 attacks, leaving hundreds of thousands of passengers stranded.

About 17,000 flights were expected to be cancelled on Friday due to the dangers posed by clouds of volcanic ash from Iceland, aviation officials said, with airports in Britain, France, Germany, and across Europe closed until at least Saturday.

"I would think Europe was probably experiencing its greatest disruption to air travel since 9/11," said a spokesman for the Civil Aviation Authority, Britain's aviation regulator.

"In terms of closure of airspace, this is worse than after 9/11. The disruption is probably larger than anything we've probably seen."

Following the Sept. 11, 2001 attacks on Washington and New York, U.S. airspace was closed for three days and European airlines were forced to halt all transatlantic services.

Vulcanologists say the ash could cause problems to air traffic for up to 6 months if the eruption continues, but even if it is short-lived the financial impact on airlines could be significant.

The fallout hit airlines' shares on Friday with Lufthansa, British Airways, Air Berlin, Air France-KLM, Iberia and Ryanair down between 0.8 and 2.2 percent.

The International Air Transport Association said only days ago that airlines were just coming out of recession.

The volcano began erupting on Wednesday for the second time in a month from below the Eyjafjallajokull glacier, hurling a plume of ash 6 to 11 km (4 to 7 miles) into the atmosphere.

Volcanic ash contains tiny particles of glass and pulverised rock that can damage engines and airframes.

In 1982 a British Airways jumbo jet lost power in all its engines when it flew into an ash cloud over Indonesia, gliding towards the ground before it was able to restart its engines.

The incident prompted the aviation industry to rethink the way it prepared for ash clouds, resulting in international contingency plans which were activated on Thursday.

Of the 28,000 flights that usually travel through European airspace on an average day, European aviation control agency Eurocontrol said it expected only 11,000 to operate on Friday while only about a third of transatlantic flights were arriving.

Eurocontrol warned problems would continue for at least another 24 hours.



AIRSPACE CLOSED

Britain's air traffic control body said all English airspace would be closed until 2400 GMT on Friday although certain flights from Northern Ireland and Scottish airports were being allowed to take off until 1800 GMT.

"When the experts give us the all clear we'll get the operation back up and running," Paul Haskins, head of safety at National Air Traffic Service, told BBC radio.

"We're working with both the Civil Aviation Authority and the Met Office (weather officials) to understand what parameters would need to be in place before it is safe to allow aircraft to operate again."

There were no flights from London's Heathrow, Europe's busiest airport, which handles some 180,000 passengers a day, while officials at Germany's Frankfurt airport, Europe's second busiest, said flights would be suspended from 0600 GMT.

Around 2,000 people slept overnight at Amsterdam's Schiphol Airport, a spokewoman said, adding they did not expect airspace in the Netherlands to reopen soon.

Eurocontrol said airspace was closed over Belgium, Denmark, Sweden, Norway, Finland, Estonia, the north of France including all Paris airports, and at airports in northern Germany and parts of Poland. Northern Czech airspace was also closed.

Polish officials said if the disruption continued, it might force a delay in Sunday's funeral for President Lech Kaczynski and his wife who were killed in a plane crash last Saturday.

Airlines across Asia and the Middle East have also cancelled or delayed flights to most European destinations.

The air problems have proved a boon for rail companies. All 58 Eurostar trains between Britain and Europe were operating full, carrying some 46,500 passengers, and a spokeswoman said they would consider adding services if problems persisted.

The Association of British Insurers said volcanic eruptions were not always covered by travel insurance for cancellation and delay, but some airlines issued statements confirming they would refund fares or change flights.

The UK's Health Protection Agency said it expected a small amount of the volcanic plume with low levels of sulphur dioxide would reach ground level in Britain later on Friday.

"This is not expected to be a significant threat to public health," it said in a statement.
