In the ski areas of New England, USA, Terry Sweeney of New Hampshire experimented with some Chanute typ. He and some friends made many flights, learned much and had fun. Their gliders replaced the older airfoils with more modern versions.

On the east coast, USA, in the summer of 1970, Robert G. Mixon of Miami, Florida, built and flew a Chanute-type biplane based on a plan found in a 1909 Popular Mechanics.

The local paper ran a front page headline “Those Magnificent Men In Their Flying Machine” on 15 June 1970. A local TV station even took some footage of a cliff launch. Mixon did it out of frustration due to the high cost of conventional flying.

Later, he offered plans, because of a large number of requests for his story which appeared in the February 1971 issue of Sport Aviation.
