Emergent day.

8°C, few showers, sun, no cycling.
Recovery: a week of undefined illness has sapped most of my energy. Now it’s lifting I can’t feel the cold, and yes I know the air has dipped below 5C. So, I spent the day recovering.
I became quite geeky later in the afternoon.
Geekiness is fuelled by a feeling. It’s a feeling with deep roots, all the way back to childhood.
With a cold like mine, any activities today had to beundemanding, so I spent time looking round Google Earth. In a few places, there are circular mountain ranges that are just too perfect a circle. With a little research, it turns out that many are impact craters. Some are as young as 3.5 million years, which doesn’t sound that old, relatively, geologically. The earth is peppered with them, though some are only detected by their gravity anomalies  One contributer has uploaded a .kml file that shows loads more. I was, by now, hooked.
And, this is where it gets geeky, I decided to see how they look in the flight simulator FSX. Some are quite clear, often a near circular lake, or an obvious crater. One, in far eastern Siberia, is not actually an impact crater but an eroded intrusive pipe (Kondyor Massif). Now it’s one of Russia’s biggest platinum mines.

late wet

Description: Trees were knocked down and burne...

Description: Trees were knocked down and burned over hundreds of square km by the Tunguska meteoroid impact.

14°C, rain which arrived late.

This is a day off work, blame backache. At one stage I had to lift my legs out of bed. These things make you feel rotten, it’s the kind of thing old folks supposedly experience.

So here I am, a little housebound so I fired up the computer upstairs. I still have some old Flight Sims files that are worth uploading. There are some compatibility problems with software that is new. GoogleEarth 6 doesn’t work properly with the scenery app FSX-KML. there is a workaround, but it’s a pain. Still, I have fixed up a file for the area of the Tunguska Event (1909). There is no real impact crater, but there is a convenient marsh area shown on GE.

The other files I fiddled with are Siberian airfields in the Sakha Republic. Some of the files are a mess of naming conventions. I don’t yet know how best to release the files. There are about a dozen airfield files in total, along with nearby scenery. Perhaps later, I may upload some pictures.

FSX scenery remains a therapeutic thing to do. I used to, years ago, get really hooked on this.
