从母亲断断续续的叙述和日后寻访中拼凑出的图景是,越南南北统一后一度大肆驱赶南方的华人,作为华裔商贾之家,他们首当其冲,一家人被反复分开审问,承受巨大的精神压力。母亲曾在市集卖布,被抓到就要行贿。后来,他们被迫迁往所谓“新经济区”艰难渡日。
“When people get hurt around our products, we need to take every ounce of education from it that we can,” Jacob Zeiger, a senior air-safety investigator at Boeing, told me, when I visited the Boeing facility this past December. “These technical findings are sacred.” Within hours of any major incident involving a Boeing plane, Zeiger and his team are notified, and they may spend a week to ten days studying the damage and interviewing the crew, piecing together what went wrong. In 2008, for instance, the engines on a 777 stopped responding, and it crash-landed short of a runway in London, shearing off its landing gear. Afterward, a team of investigators re-created the plane’s fuel system in a Boeing lab. A small heat-exchange unit, they found, had accumulated ice during the flight. Every 777 has since been retrofitted with a new version of the unit. Thanks to decades of such refinements, today’s jets may be the world’s most reliable machines. Flying in them is less likely to kill you than walking on staircases.
