I am staring at a GE First stage turbine blade as I write this.
Good to hear from someone that is not a meteorologist or vulcanologist (or politician) on the possible effects. For once some relatively sane observations between the "Don't fly it's risky" and the "To hell with it, let's go"
My only point so far is that the decision should be left to those best able to make them:
1. Airlines
2. Insurance firms
3. Pilots (w butt at risk)
4. PAX (idem)
Having zee Govt making the calls means vanilla for all, wether you like it or not.
