May 29, 2012 is 75th anniversary of the Golden Gate Bridge opening. Until the Verrazano Narrows Bridge in 1964, Golden Gate was the world's longest span at 1280 meters. From anchorage to anchorage the Bridge is 1970 meters, nearly two kilometers long.
On Saturday another wonder, the Battleship USS Iowa sailed beneath the Golden Gate on her last voyage. Iowa will be on permanent exhibit in San Pedro, California. Seeing this bridge and battleship together, we can believe that humans can built giant starships.
