Golden Gate Bridge wanted it to be painted with black and yellow stripes to ensure visibility by passing ships. Senior engineer Charles Alton Ellis, collaborating remotely with Moisseiff, was the principal engineer of the project. Moisseiff produced the basic structural design, introducing his "deflection theory" by which a thin, flexible roadway would flex in the wind, greatly reducing stress by transmitting forces via suspension cables to the bridge towers. Although the Golden Gate Bridge design has proved sound, a later Moisseiff design, the original Tacoma Narrows Bridge, collapsed in a strong windstorm soon after it was completed, because of an unexpected aeroelastic flutter.
Suicides at the Golden Gate Bridge had long been proposed. The Golden Gate Bridge, referred to by Krista Tippett as a "suicide magnet", is the second-most used suicide site/suicide bridge in the world, after the Nanjing Yangtze River Bridge (see List of suicide sites). The deck is about above the water. After a fall of four seconds, jumpers hit the water at around 75 mph (120 km/h). Most of the jumpers die due to impact trauma. About 5% of the jumpers survive the initial impact but generally drown or die of hypothermia in the cold water. Most suicidal jumps from the bridge have occurred on the
