Ash clouds threaten air traffic

[bravolima553]

Hi all,

personally I´m more on the restrictive side. Nobody knows exactly how to compute this "cloud* and how to deal with different concentrations in it. In the last 50 years we never had such a occurence over Central Europe.
I'm wondering, beside the reports of the finn F18´s, have there been any reports or remarks from flight crews around, regarding volcano activities over Europe in the last few day? Do some crew encouter subtle indications of ash in the air, especially in the night before grounding?

thanks
