According to CEO Bernard Van Milders the decision is pure panic football. "In a volcanic eruption, all harmful particles already after a few 100 km from the ash cloud disappeared." "Then there remain only harmless tiny particles and water vapor on the traffic just will interfere. On the surface, there is no trace of any precipitation of harmful dust to be found. We suspect that this decision was taken by a European officer without relying on scientific evidence and we find this unacceptable, "says another.
In the past 30 years, more than 90 jet-powered commercial airplanes have encountered clouds of volcanic ash and suffered damage as a result. The increased availability of satellites and the technology to transform satellite data into useful information for operators have reduced the number of volcanic ash encounters
Volcanic ash is composed of particles of glassy pulverised rock less than 2 millimetres in diameter. When an aircraft flies into it at its high cruising speed, the cockpit windows get a sandblasting, obscuring the pilots' view.
Crucially, though, the engines suck the dust in, where it melts in the hot combustion chamber and fuses to form globs on the turbine vanes that block the engine airflow. Only when it cools and solidifies - as the aircraft plummets engineless - can enough of the muck flake off to allow an engine restart

I think your just trying to convince yourself there is a conspiracy when there obviously is not.

So what is the real reason?
Airlines complain that the authorities have not measured the ash concentration in the air
