Most UK aeroplanes will remain grounded until 01.00 on Saturday and the ash from Iceland is reaching the ground in some parts of the UK. The plume is thought to be harmless but people are warned to monitor symptoms.
Some flights have been allowed in and out of Glasgow and Belfast until 19.00 and there is news of some flights into and out of Norway.
Yes, Ryzine is closed, donno about Vienna..
I think you could extend list of countries affected….for example Germany and Poland is also affected (they are thinking about to pospone funeral of president Kaczynski).
Even in my country – Czech Republic – the only big airport – in Prague – is going to be closed from midday.
As I proposed in my previous comment – Iceland could be a pioneer in “geothermal army forces”:-)))
