How Dangerous Was the Volcanic Ash Cloud?

Posted May 11, 2010 7:48 AM

According to the UK's Daily Mail, satellite images now reveal that the air space over Europe was closed for nearly five days under false pretenses — the ash cloud resulting from a volcano in Iceland was "nearly undetectable" over Britain. More than 100,000 European flights were cancelled, costing the airline industry nearly $2 billion. The government says it had the safety of the public in mind when it made the decision not to allow flights. Would it have been risky to fly? Or was it irresponsible to ground everyone? Should governments be held accountable, and to what end?

Once again the correct course of action is clearly visible, after the event.

Of course the responsible authorities had no choice, they had to act to ensure public safety. What else could they do? Gamble with the lives of thousands of people?

My engineering institution's magazine asked this same question and the majority of respondents said it was the right decision - although many commented that it took too long to fully analyse the dust and declare it safe to fly.

My comment was that in their shoes I'd rather deal with a horde of irrate and late home travellers than with the relatives of late travellers who were mistakenly told it was safe.

Hi,

if the authorities have to act towards total safety then I expect total and permanent closing of all streets - no more motor traffic allowed.

I don't believe anything written the the Daily Mail (Daily Heil). The newspaper(Sic) tries to develop a hysteria over everything. Thank God for the sensible answers so far.

I think it was RAF F-18's, but could have been a different air force and different aircraft type, that flew through a known ash-infused region during air space closure and came back with pitted compressor parts. The risk was real, the popular media (not sure how sleazy Daily Mail is) is full of it as usual.

That's what the caption for the source photo reads, but I am skeptical. I always thought the shock wave is behind a supersonic aircraft. And, can it be wise to break the sound barrier close enough for a ground-based photographer to catch a picture? We've got regulations against that sort of thing, though the caption indicates the photo was taken from the deck of a ship, presumably at sea.

I suspect the image shows the shock wave of a high subsonic aircraft causing condensation of the air the jet's passing through, which can happen instantaneously and still looks cool.

Hi,

I heard about F16's from Finland, you are right that the turbines were to be overhauled,

but they did make a flight around Iceland and there was no information about the quantity of ingested "ash".

Lufthansa and Airbus-Industries made bot 4 hour tours inside the "cloud" over central Europe, no report about any damage.

Think about safe landing in desert storms with a lot of dust and sand in the air.

Turbines are safe for this, but not with very long life.
