Volcanic Ash

My sympathy goes to anyone who is having their business trip/holiday ruined by this.
The only thing that concerns me is that I have heard (informally) about at least two mega European airlines that have a firm and tested view that the risks have been hugely exagerated.
They have sent their own test planes up and they have returned without a scratch.
I hope we are not all causing ourselves so much pain for possibly nothing.
I feel it too as my long haul holiday is supposed to start in days.
