This is the shade used by NASA. The Bell X1, the first airplane to break the sound barrier, was also painted in International Orange. Above is displayed the tone of "international orange" used to paint the Golden Gate Bridge. The tone of international orange used to paint the Golden Gate Bridge is slightly lighter than the standard International orange used by military contractors and in engineering (shown below), thus
Golden Gate Bridge Although the idea of a bridge spanning the Golden Gate was not new, the proposal that eventually took hold was made in a 1916 "San Francisco Bulletin" article by former engineering student James Wilkins. San Francisco's City Engineer estimated the cost at $100 million, which would have been $2.12 billion in 2009, and impractical for the time. He asked bridge engineers whether it could be built for less. One who responded, Joseph Strauss, was an ambitious engineer and poet who had, for his graduate thesis, designed a railroad bridge across the Bering Strait. At the time, Strauss had completed some
