A few years ago scientists were surprised by the sight of two planes carving a hole through a cloud—which then began spewing snow.

A new study spawned by the accidental discovery solves the mystery behind so-called hole-punch clouds and explains how airplanes can change the weather, at least on an extremely local level.

interestingly I've never made it past Edinburgh, something I intend to fix on my permanent return to the UK.

We're staying at Clava for the first couple of weeks, near Culloden Moor, it was settled by Neolithic man, there's a couple of burial cairns there, plus several standing stone. Situated in the Nairn valley, you can see why early man chose to settle there. We have a self-catering 'cabin' for two weeks, the come back to Dumfries and Galloway for a week - somewhere we've only ever driven past on the way to the real Scotland. Time we explored. :) Back home via the Lake District - retirement has its advantages. :)
Slainthe!

I've been right up to the top of Scotland as far as John O'Groats which looks remarkably  similar to Land's End.   :woot:  I've even visited the Orkneys but have yet to set foot on Shetland.  One day!   :laugh:
