Al,
Thanks for the email with the attached scan on the story. The scan I could read but the print on the post above was too blurry to read once I “blew it up.”
I think you told me that it was in a Dense Pages book about a Tony Barton account about what to do to secure a hang glider in the event of a dust devil.
The picture shows a dust devil behind the glider and drifting to the right of the picture. (Moving from behind the glider to in front of the glider.)
Assuming (oh boy,) that the general wind is not too strong to have a hang glider set up in, it has been my experience that most dust devils will locally over power the general wind (prevailing wind of the day).
In the picture shown the dust devil behind the glider would be pulling the wind into the front of the glider. At this moment (instant) the pilot would be better positioned at the nose of the glider.
Where the pilot is, near the tail of the glider, would tend to pole vault the nose of the glider up and over the tail and toward the thermal. (Dust devil.)
Once the thermal centered over the glider most often they wind up standing on their nose and spin like a top if someone (or two) is/are hanging onto the nose.
I’ve seen this happen several times at Chelan Butte, Washington. It can be a captivating scene of determination, hopelessness, and fear. (If we could see the air we flew in, we wouldn’t! ---Unknown.)
I remember during the Women’s Worlds as a lane marshal I told Campbell Bowen (sp) he might want to unhook from his ridged wing for the dust devil behind him. He looked over his glider, slack jawed, at the dusty spectacle. Two pilots on the nose of a glider were being spun around and around on the ground while the glider was standing on it’s nose with the keel pointing straight up the core of the thermal.
If the dust devil was out in front of the glider, in your posted picture, then I would agree with the pilots position Al.
Pilot Steve Ford told me what worked for him. Stay on the nose when it goes tail up grab the king post, or keel if it’s a topless gliders, and hold down and run around and around with the spinning glider until the thermal dances away. A “Ballzy” move that I just don’t have the heart for.
From what I've seen if it was my glider I would try to save it and scream for help. If it was someone else’s glider I’d just say, “I couldn’t understand what you were screaming! You should speak more calmly next time.”
So I may or may not be right about this, Al, but perhaps this will open up the can and we can gain more input from the vast pool of experience out there.
