Description
Photograph of Frederick Marriott's "Avitor Hermes Junior" airship test flight on July 2, 1869, near San-Francisco, CA. The "Avitor Hermes Junior"airship hovers over about 15 handlers and spectators and is described as "Steering Balloon Entry 70." Its rudder and and ailerons stick out at right. It was designed and built by Frederick H. Marriott. "The "Avitor Hermes, Jr" was powered by a steam engine, having one 2" diameter cylinder with a 3" stroke, which was capable of generating 8 pounds of steam. The engine drove two two-bladed 4 ft.-diameter propellers, each mounted within one of two flat wings. The Avitor Hermes, Jr., 37 feet long and 14 feet in overall width, was designed as the test version of what would have been a passenger-carrying airship. On July 2, 1869, the 1,360 cu. ft. Avitor Hermes, Jr., was tested under power on a tether at Marriott's Avitor Works, located adjacent to Shell Mound Lake near present-day Millbrae, just south of San Francisco" -- Unknown author.
