If you have additional information (ex: specificity of piloting, various characteristics...) on the hang glider Unknown / Inconnu by Moyes, you can supplement his card by adding your comment or write to us :
That is John Dickenson flying his Frigate Design. The glider was built by Bill Moyes.
I have 14 colour photos here, and there was an article in Skysailor.
Bill didn't think it was worth the hassle to build and set up, but then Bill didn't want anyone to know who John Dickenson.
