Dear De Havilland Driver - thank you so much.
Your reply is the first time a pilot, on this supposed pilots network, has mentioned that something is actually out there.
The events that have spectacularly disrupted aircaft in flight (BA in Indonesia, KLM in Alaska, etc) have encountered the full force of the volcanic eruption.
Given that this 'cloud' has travelled two thirds of the way around the world, have the pireps been able to calculate or estimate the density of the volcanic pumice particulate matter?
Given that abrasion damage is based on density of pumice, speed and time of exposure - I wonder how serious the cloud is?
As I said previously (may have been on a separate post) - I just can't see any visible evidence of the 'cloud' everyone is talking about...
