To mark the 100th anniversary of that service, three vintage biplanes will retrace the pioneering west coast airmail route, Contract Air Mail 8 (CAM 8), from San Diego to Seattle, with a stop at Buchanan Field on May 15th.
The flight will use three Stearman Speedmail biplanes, as used by several airlines as mailplanes in the early 1930s. Powered by 450 horsepower engines, the wood-winged and fabric covered open-cockpit aircraft were noted for their dependability and ability to carry heavy loads. Of the 41 built, seven still fly, so the CAM 8 flight will be a rare chance to see these aeronautical pioneers at work.
On the morning of May 15, 2018, from 9:00 AM to 11:00 AM, the celebration flight event will be open to the public with a presentation to honor the significant contributions the airmail pioneers made to the modern airspace system. The event is located at Buchanan Field Airport at Pacific States Aviation: 51 John Glenn Drive, Concord, CA 94520.
