As I have always stated I will fly when those more informed tell me it is OK to do so. Thats how the safety system is supposed to work.
That's exactly what I seriously doubt. Decisions were made on assumptions, computer models, etc. There is no system in place to actually measure the amount of ash. (all said before)
A cloud has to be visible otherwise it's not a cloud. If there are invisible ash particles in the air it's more like an 'ash bubble' ..........
It's been a very expensive over-reaction
