We had an HGFA Instructors conference May 22nd-23rd in Melbourne.
Molly and I attended with approximately fifty instructors. The guest speaker was
John Dickenson.

John had the opportunity to show his photographs from 1963, showing that he
had developed the first conical wing hang glider. He was pleased to have the
opportunity to show his work and receive the congratulations from the HGFA.

John suggested to me that he would like to see the hostilities disappear and I
agreed.

Rogallo: We have all seen films where a much younger Francis Rogallo glided a
small conical Rogallo wing across the room, and if that’s all he did, it was
enough to inspire John Dickenson to build the airframe and gravity shift system,
that has given us our delta glider.

I won’t enter the discussion of who named it the Rogallo wing and if it should
be called the Dickenson wing. Maybe Dickenson glider…

Having known Francis Rogallo for 35 years I’m comfortable with the name Rogallo
wing and also Dickenson glider.

I’m writing to Stephan Malbos suggesting that we present John Dickenson with the
FAI gold medal at Forbes in January at the World Championships and I would like
to see the end of this discussion.
