Re: Glide ratio beyond the curvature of the earth.
I guess you would be in orbit at that point, right? I did the math first, then checked wikipedia. We had almost same answer: beyond a 3,750:1 glide. If a top notch 31m glider has a 70:1 glide. That is still 50x short. Unfortunately, this isn't true. Why? Because as one moves forward, the gravity ve...

Yosemite LZ is dry (mostly), Bridalveil campground is open
The campground is open. The LZ is nicely landable. The "creek" that runs across it near where most folks do their base-leg still has water in it, but otherwise, all is fine. I flew on Saturday and had a lovely view. Yosemite falls has more water than I've ever seen in it. However: There w...

The National Park Service web page for Yosemite just today (14th) listed Bridalveil Campground as opening on July 15th. (Tomorrow) They also have the water level down to under 5 feet gage height. I assume that means that we can at least camp. Flying also looks possible, but not yet a definite. Those...

So far, the only 1st come 1st served campground available in (semi) reasonable distance to launch is Tamarack Flat. Boil the water (you get it from the creek) or bring your own. No trailers or campers. I'll keep watching. I still plan on going, flying or not, especially since I'm going up Thursday (...

I'm going no matter whether there's flying or not. My kids go back to school two weeks after my scheduled monitoring, and I have commitments the following weekend, so that's my last chance to go to Yosemite for the year. So, short of some emergency, I'll be there July 23/24. Contact me if you want t...

Average depth of the ocean is several miles (don't know the exact depth, assume 3 miles.) Earth is 4000 miles in radius. Water covers about 3/4 of the surface, so that works out to a rough estimate: 1/1000 of the earth's radius is water. Volume is 4/3 Pi R^3, so as you can see, the volume of surface...
