马航失联客机可能被手机劫持As the search for the missing Malaysia Airlines Flight MH370 continues, investigators have come across some startling evidence that the plane could have been hijacked using a mobile phone or even a USB stick.马航失联客机 MH370 的搜救工作仍在继续，与此同时，调查人员惊讶地发现，飞机可能是被手机甚至 USB 设备劫持。 The theory comes from a British anti-terrorism expert who says cyber terrorists could have used a series of "codes" to hack the plane's in-flight entertainment system and infiltrate（渗入） the security software. According to Sally Leivesley, a former scientific adviser to the UK's Home Office, the Boeing 777's speed, direction and altitude could have been changed using radio signals sent from a small device. The theory comes after investigators determined that someone with knowledge of the plane's system intentionally flew the jet off course. "It might well be the world's first cyber hijack," Leivesley told the U.K.'s Sunday Express. "This is a very early version of what I would call a smart plane, a fly-by-wire aircraft controlled by electronic signals." Leivesley said that the evidence increasingly indicates that someone took over the plane's controls "in a deceptive（迷惑的） manner" and overwhelmed the plane's system either remotely or from a seat on the plane. "There appears to be an element of planning from someone with a very sophisticated systems engineering understanding," she said. "When the plane is air-side, you can inset a set of commands and codes that may initiate, on signal, a set of processes." Investigators have also proposed that the pilots themselves could have switched the plane's communication equipment off and redirected the plane west, but officials say it...
