This post was written a few years ago, but it still worth the read. It is a small history of the Bay Area of which many may not have known. The author, Sarah B., is a resident of the Richmond District and she discusses the various aspects of the Bay Area. Sarah decided to visit Hiller Aviation Museum in San Carlos and something caught her eye to which she wrote about. The theme of this article is about one of the first tractor propeller designs in Northern California. Known as the “Gonzales No. 1 Tractor Biplane” two 15-year twin brothers, Will and Arthur Gonzales, built their biplane glider and flew over the Richmond District. Sarah has included some great pictures from the archives to retell this fascinating piece of Northern California aviation history.
