...or maybe the Knee-jerk reflexes have finally exhausted themselves?
...or maybe enough real data has been collected to give the 'authorities' sufficient confidence to offer risk-based advice rahter than 'CYA and let someone else make the first move' stuff seen so far.
Still don't see much more CONCERTED ACTION to collect more data about the EXTENT and PARTICLE DENSITIES of the ash cloud. This was mentioned several times yesterday. Point to point flights by single aircraft are (usually) more to do with
PR than serious scientific data collection. At least UK sems to have had TWO science-based flights - 'Swindon-based' NERC plane (flying from ??) and Cranfield. We should have AT LEAST five aircraft, doing several flights a day EACH on different tracks with different planned ash exposure, if there was any proper programme to collect data about the changing position and height of various components of the ash cloud AND the longer-term effect on turbines.
