responsibility for making decisions has been increasingly farmed out to independent experts.
Ironic that experts are the airlines themselves who set the safe level they so objected to.
CEO's who complain AFTER a well know, serious, threat to their business occurs are incompetent. I do not want politicians making important technical descisons, especially about safety, because they are unqualified, incapable and biased towards making the unsafe choice. If it was a political decision the airspace would have re-opened within hours against all advice.
