It's not just Scotland.

I see that BAA are suspending all flights out of Heathrow and Stansted.

(Looks out of window)

Is that just overcast, or is it volcanic dust?

Looking at the map, they appear to be following the precautionary principle, so we probably don't actually have dust over us right now, not down here, but they don't want to send planes up into something that might cause severe damage to turbojets. (Not since the scary time a 747 lost all 4 engines and nearly came down as a result.)

ETA: following crazyscot's link will bring you to this page of graphics file links, of which this one shows the latest forecast.

ETA: farewell, Denmark. They're closing their airspace at 1600Z.

Yup airspace closed for at least six hours, I reckon they'll actually keep it shut until at least tomorrow morning. So on the plus side, less noise, less pollution from the planes, on the downside...

Ban volcanos have you see the pollution they cause!!!!

Ah, joy.

I hope it clears before noon Monday, GMT -- that's when we're due to take off on a 777 from Narita to Paris CDG, en route for Edinburgh!

Joy indeed.

It could be very interesting - if you look at the map on the BBC article, you can see that the main plume is heading along the north coast of Scandinavia. When we flew back from Narita to LHR, our flight path was pretty much along that densest bit.

I'm not sure if your outbound went along the same geodesic - perhaps the route from CDG is starting further enough south to path differently - but I certainly hope this clears before your return.

You know of my irritating sister... she was on the 1985 flight that had to land at Jakarta - she'd been on holiday in the UK and was on her way back to Perth (she was only 17 at the time). Mum and Dad got a phone call from the airline at silly o'clock (something like 3am) from the airline to "reassure them that she was okay and would be put on a flight to Perth as soon as possible. As Mum and Dad had, at the time, no idea that there had been a problem at all, this woke them up somewhat.

On the bright side, we are promised a few evenings of fantastic sunsets.

That happened in Alaska when I was a teenager. The volcano across the inlet from us went off, spewed ash five miles into the air, it got snatched north in no time, a plane leaving Fairbanks had no idea the cloud up ahead was ash, flew in, all the engines quit, and they fell two miles before they got the engines started again.

Ever since I heard about that I could never decide if I would 1. fly everywhere for the rest of my life, because the chances of that happening again were so infintesimally small, or 2. never ever ever get on a plane again. :)

Presumably that was KLM Flight 867 getting tangled up in Mt Redoubt's plume in 1989.

As far as I can see, that incident and the one that megabitch's sister was involved in are the two famous cases, and I'm not aware of any others, presumably because airliners treat volcanic plumes with a lot more respect these days. And it's not as though they're going to be unaware of them, either. A volcano uploading a few cubic km of ash into the atmosphere tends to get noticed.
