Peter, I am a jet engine engineer and as I've said before, none of us can find any evidence of damage. Any other engineers out there found any damage?
As far as I'm aware, ash has never caused the loss of one airliner. Birds on the other hand bring them down a fair bit. But we don't stop flying because a weatherman saw a couple of ducks in the air.
These ash regulations will make European aviation the safest in the world; because if they carry on there won't be an aviation industry left in Europe.
