There were several air fields in San Diego, California that should be
considered in the WW I airfield study. U.S. Army Air Corps, Rockwell Field was
subsumed by Naval Air Station North Island and good documentation exists in a book
titled "From Jackrabbits to Rockets," but I forgot the author. That airfield
had linear landing strips. Claude T. Ryan had an airfield at Dutch Flats, across
San Diego Bay, that did not have a form. Dutch Flats later became Lindbergh
Field, which was built by Lester Olmstead in a circular form. Some time in the
1930s, it assumed a linear design. The San Diego Aerospace Museum should be a
treasure trove of information for this study.
