New Hang Gliding History Web Site: https://hghistory.org/
If you search the U.S. Hawks for "Everard" you'll find a few hits throughout the years. Most will reference the work of "Everard Cunion" and his extensive hang gliding pages available at https://everardcunion.com.
In a recent announcement, it was noted that the hang gliding history section of that site now has its own URL: https://hghistory.org/. Happy surfing!!
