Rain rain

We had planned to go out for dinner and shopping, but the gloomy cold rain at sunset put us both off and we stayed in. Watched Ken Burns' documentary on the Shakers, which I'm sure I'd seen before on PBS but Gary didn't remember it. Certainly a fascinating but melancholy story, and missing 25 more years of history since it was made in 1984 and featured interviews with three surviving Shaker women.

We decided that we want to see his Brooklyn Bridge documentary, and Lewis and Clark. Looking at those on Netflix I also added Thomas Jefferson and the one on the history of broadcast radio. Not for all at once though.

Weather sounds unpleasant for the entire weekend. I should stay in and weave, and maybe cook soup or something like that. We shall see. Gas prices are rising so fast that I'm inclined to drive nowhere that isn't essential. I'm worried about the effect on the prices of groceries though, not to mention hay if this continues.

With you on the gas prices. They are now so high here, that I heard overheard neighbour openly wondering if it's worth him driving to work. This is now a very serious situation; if it's making a median earner (such as me) itch, how badly is it hurting those with less wealth, like my neighbour? And there are a fair few people like him in the UK.

That is what worries me also. However I think I am more disappointed in how such a regression is being applauded, rather than met with derision.

I hope the weather's improving. Gloomy wet weekends are no fun.

This afternoon I've been watching the APRS track of iHAB 3, a balloon launched from Ottumwa earlier today. I'm wondering, given its apparently rather slow ascent and relatively rapid eastward motion, what its chances of landing in Lake Michigan are...

Hmmm... At present this view gives a slightly better historical track, as the balloon's been in the air for several hours. At the moment it's over Belvidere, and looks as if it's wondering whether to follow I90 to Chicago or to head across country to Marengo and Woodstock... ;)

I mentioned it at least in part because I recognised a few names you've mentioned, and figured it wasn't that far from you. ;)

At present the balloon's descending rapidly. Presumably its chute will start having an effect soon, and then it'll drift on the wind for a bit, but it looks as if it might land on terra firma rather than in the lake... maybe.

Yep. It turned South as it got close to ground, and seems to have ended up somewhere between Johnsburg and McHenry. Still half a chance it ended up in water, though...

Seems it landed conveniently near someone's front door, as marked on this aerial photo. I presume that means it was recovered successfully.

There's a bit more detail on the flight's website now. Photographs there show the payload hanging in a tree, and being recovered. Also some suburban brats. ;)

One of the balloon crew reported (in #highaltitude on FreeNode):

"iHAB-3 was a floater, staying aloft for 6 Hours - 26min, reaching a burst altitide of 79,102ft and traveling 234 miles down range. We received signal reports of the 20 metre beacon from accross the United States and Canada. Many operators from Iowa, Illinois and Wisconsin had the opportuinity to make contacts via the VHF simplex repeater."

It's arguable whether they actually got the balloon to float (as that usually implies it stays at a more or less constant altitude for a while) but they did manage to get it to rise very slowly. There was quite a bit of anxiety during the flight about whether it'd come down in Lake Michigan, and much relief when it didn't.

Eventually balloons burst, usually when they can expand no further in the thinning atmosphere, though sun and cold have some influence too, especially on longer flights. Other balloon flights I've monitored have burst between 75 and 110 thousand feet up, so this was on the low side of average, height-wise, but was also aloft rather longer than average. Once the balloon bursts the payload tends to fall very rapidly until the air gets thick enough for the 'chute to slow it down.

The chase crew were at the landing spot about twenty minutes after the balloon landed, and apparently the six kids got a finder's reward of ten bucks each... ;)
