A salutary reminder of the power of nature
This is being written at 15:00 UTC on Tuesday, 20th April. It’s still anyone’s guess as to when the airspace that commercial aircraft fly in will be free from volcanic fallout.

Based in Arizona but planning to fly to the UK in about three weeks, it’s also very frustrating finding really good, accurate information to help one think through plans and back-up plans.
But here’s a web site for UK glider (sailplane) pilots that goes a very long way to providing really solid information. Check it out. (And, once again, thanks to Yves Smith of Naked Capitalism for finding the site.)
Well done GlideMet.
