Hello, I found the video in youtube.com that you're looking for deaf hangglider. I had been hanggliding since 1989 and paragliding since 1985. I wa...See Mores an instructor and taught 5 deaf pilots. Now I now no longer fly hanggliding and paragliding due to my illness from breast cancer. Now i am flying my ultralight trike. It's similiar to hanggliding with seat, engine and propeller. You might want to contact me. I had taught Craig Uyeda to hanggliding. Now I fly ultralight trike.
