Between San Francisco and Sunnyvale, I visited the Hiller Aviation Museum at San Carlos, alongside the highway and the local airport. This is a very interesting museum, all about innovation and pioneers, including of course Stanley Hiller and his helicopters, but also about all aviation pioneers and inventors of California, from the 19th Century attempts to Burt Rutan's designs.
http://www.hiller.org/Access is very easy, facilities are nice and the collection is amazing, with a unique flavour of creativity and daring spirit.
For instance I discovered this Avitor by Frederick Marriott, the first powered, lighter-than-air unmanned craft to fly in America, in 1869:
Gliders:
Echoing to an exhibit visible at the Oakland Aviation Museum, I also learnt about Feng Ru, the first Chinese aircraft designer and aviator, who immigrated in California and became the first man to fly an aircraft in the Western United States, in 1909:
An airworthy replica of the Wright flyer which flew from New York to
California in 1911, achieving the first transcontinental flight:
A similar replica is visible at the Oakland Aviation Museum.
At the Hiller Museum, there is also another replica of the Wright Flyer, and an exhibit about Robert Fowler, the first aviator to achieve a transcontinental flight from West (San Francisco) to East (Florida) in early 1912, and to cross the Panama canal.
One of the most notable exhibits is the Curtiss pusher replica flown by Eugene Ely, the first to land on a ship in San Francisco bay in 1911, thus paving the way for future aircraft carrier operations:
There is an incredible collection of special aircraft, such as this one for urban surveillance:
The robotic, unmanned, secret spyplane Boeing Condor, nearly stealth:
Some fun stuff:
And of course the Hiller helicopters:
More conventional stuff too:
Ant to conclude, the Hiller flying platform from 1955:
