Back one page on this thread check the video where I was checking Robin's U2 for turns. It turned out to be high siding in a thermal and not an out of tune glider.
Anyway the landing was almost a high speed digger due to turbulence in the LZ when the right wing dropped.
I played the video and stopped it where my right hand wheel was only inches from the ground and made a photo with the "Snipping Tool."
I'll attach the photo below. It shows a still frame of a possible neck breaking close call.

I would estimate my ground speed at the time of that picture frame to be at least 35 mph maybe more.

I am REALLY glad that you made it out of that situation, Bill. I have a tendency to deprone early, just to make sure that my landing gear is always the first thing to hit the ground. It slows down my air speed and probably reduces my maneuverability. But it seems safer to me.

Magdalena Rim NW of 'Cruces NM 7-25-17

RGSA/Hawks,
Robin will be at my house at 10:30 am (Tuesday) to pick me up as driver, photographer, launch assistant, chase retrieverman (new word.)
I'm hoping to test out my home made Pop Sock (camera wind cover sock). I'm hoping to capture real time vario and radio sound with not as much wind noise as in previous YouTube videos. So more than ever I want Robin to stay up to give me some radio chatter. I'm also hoping his microphone foam will work on his end but we'll see/hear.
If the vario and radio are too loud that will confirm my suspicion that the microphone on my GoPro Hero3 (white) has an automatic gain control built in. Recent video posts had the communication radio volume all the way up for the earphone plug that goes through the hole of the camera case.
By surrounding all but the camera lens with U-Haul dish packing foam I'm hoping the wind noise will be reduced. That in turn may automatically increase the mic gain. If it does I can then cut back on the radio volume and partially plug the hole in the camera's trapdoor where the mini vario is mounted with Velcro.
I also padded my camera mount so as not to pick up as much glider frame and wire vibration noise.
A real primitive, cheep Scott's Irish, application with stuff I had on hand except for the U-Haul foam package ($8.50)

Bill and I went out with our friends Kerry and Demetree today, July 25, to Magdalena Rim. It might have been good for PG's, but was pretty light for hang gliders. A sunny day after a weekend full of rain, and a sky full of puffy cumulus in all directions. Winds were south-southwest, but anywhere from 0 to 12 mph. Temperature at launch was close to 90 degrees F. I launched about 1:45 pm MDT and had a 3-minute sled run in mild, non-turbulent air. Thermals were too small to work (which is where PG's might have had a chance) and I barely made it around the Cone to set it down in the Arroyo LZ. Had a perfect landing, though, and, hey, it was a flight! My thanks to Bill, Kerry and Demetree for making it all possible! With blue skies and storybook cumulus, it was a lovely day to be out in the wild west.

PS - There is too much mud and water on the dips in the Corralitos Ranch road to drive it with anything but a vehicle with good clearance. I sure don't recommend it for, say, my Toyota Corolla, at least until the mud gets cleared away.

This flight was also a test flight for my audio capture of radio communications and also the mini vario mounted to the back of the GoPro Hero3(white) camera. I had drilled a small 3/16" hole in the camera's trapdoor and with Velcro (with holes also punched in the hooky and fuzzy pieces.) I fastened the mini vario to the GoPro trapdoor case. The earplug coming from an extra radio (eventually to be located inside the double surface) was plugged into a hole I drilled in the GoPro case as close to the camera's microphone as I could get it.
I also padded my camera mount to reduce the vibrations getting to the camera from being fastened to the keel.
The latest modification was to put U-Haul dishware packaging foam around the camera case with only the camera's lens showing through the foam pad.
We only got a short flight testing of this set up but I've been making steady progress picking up audio during the hang gliding flight.

That was a very instructive video, Bill. Thanks for doing it! Looks like I was too far from the hill, for most of the flight - though there might have been no lift there, either. A beautiful day, though, and I think that Demetree and Kerry had a fine time watching it all. Thanks to everyone for making it happen!
