Critics have blamed outsourcing for the company’s recent lapses: some twelve hundred suppliers design and manufacture parts for Boeing planes. “There were a number of issues that we had,” Larson said. “But we’re coming out of that. We can’t build airplanes fast enough.” He walked me over to a half-finished 777 that was about to have its wings attached. “I remember my very first fuselage join,” he said. “The mechanics drilled about eight hundred holes, then started inspecting the skin around them. I thought, This is going to take forever!” The wings have to be mated to the body with gaps of five- to ten-thousandths of an inch. Then they’re bolted on with just enough torque to flex and hold fast, even in the most severe turbulence. In Boeing’s stress tests, they can bend almost forty-five degrees and snap back, and withstand years of flexing without structural fatigue. “It’s not a piece of farm equipment,” Larson said. “It’s a life-support system. At thirty-five thousand feet, you can’t pull over.”,推荐阅读搜狗输入法下载获取更多信息
音頻加註文字,高市早苗「台灣有事論」為何引起北京強烈反彈 ?陳宥樺教授向BBC分析,冷戰結束後很長一段時間,日本防衛重心主要集中在北海道,反映當時來自莫斯科的威脅。但大約2010年前後,在野田佳彥首相任內,日本開始將戰略重心由北海道轉向西南地區。「這一區域從九州南部延伸至奄美大島、宮古、石垣與與那國,長期以來是日本領土防衛最薄弱環節,兵力最少,卻在面對中國威脅的最前線。」
