this is the original galloping gertie's 1940 bridge.ou can see the two eight-foot-deep section. >> many lessons are learned from fw ertie's demise, including how critical aerodynamics are in building suspension bridges. >> there really wasn't a major suspension bridge built until the replacement in 1950. and many of the things that exist on the 1950s bridge are a tribute to better aerodynamic stability. >> in 2007 a twin bridge is completed. the architectural look of both structures resembles the original gertie, a tribute to her grace and elegance. >> so that new bridge as well as others have been constructed since 1940 are part of galloping gertie's legacy. >>> coming up -- an iceberg implodes in front of a group of tourists sending them scrambling for safety. >> we're all shouting and screaming. >> when "caught on camera: watch out" continues . flying is old hat for business travelers. the act of soaring across an . in a three-hundred-ton rocket doesn't raise as much as an eyebrow for these veterans of the sky. however, seeing this l
