Why? Because at the end of the day, the students at my school felt one shared experience -- our politicians abandoned us by failing to keep guns out of schools. 160

While the true need for the bridge is disputed, it is undeniably an extraordinary feat of engineering.Built to withstand a magnitude eight earthquake, a super typhoon, and strikes by super-sized cargo vessels, it incorporates 400,000 tons of steel -- 4.5 times the amount in San Francisco's Golden Gate Bridge.Guo says the most technically difficult aspect was the construction of a four mile (6.7 kilometer) long submerged tunnel.The tunnel is a crucial component because the Pearl River Delta is one of the busiest shipping areas in the world. According to the Hong Kong-Zhuhai-Macao Bridge Authority over 4,000 vessels -- everything from passenger ferries to container ships -- cruise its waters every day.Guo explains that the tunnel is made of 33 "elements" -- huge hollow blocks measuring 590 feet (180 meters) long, 125 feet (38 meters) wide and 37 feet (11.4 meters) high. Each element weighs 80,000 tons -- about the same as an aircraft carrier. The elements were precast on Guishan Island, near Zhuhai, and transported to the construction site by floating pontoons and tugboats. "We excavated a foundation trench in the sea bed, laid a rock bed, then immersed the elements," he says.The tunnel runs between two artificial islands, each measuring one million square feet (100,000 square meters) and situated in relatively shallow waters. Building islands from scratch didn't prove easy, either, says Xinglin. A structural frame was created using 120 giant, hollow, steel cylinders, each one 180 feet (55 meters) high (equivalent to an 18-story building) and weighing 550 tons -- about the same as an Airbus A380, the world's largest passenger jet."The steel structures were manufactured in a workshop in Shanghai and then transported to the site by ship," Guo tells CNN. The team used hydraulic hammers to drive the cylinders into the seabed, then filled the cylinders and the enclosed area with sand. 1915

Witnesses described the surreal scene after the plane left the airport. John Waldron was walking along a trail near the bay when he noticed the two military jets following a plane doing aerobatics."I thought they were practicing for an air show," he said.After the plane approached Ketron Island, Waldron saw a thick column of smoke followed by a loud explosion, he said."Everyone was literally frozen in place, muttering about what possibly happened," he said.Kathleen Reichel said she watched the planes pass by for about two minutes."My husband and I are recently former Boeing employees, and we were wondering why a jet was near the passenger airplane," she said. "We heard the jet because our windows were down while we were waiting in the ferry line to go to Anderson Island, which is adjacent to Ketron Island." 818
