The legendary【C2】______(invincible)of the famous box is familiar to most of us. Yet for such a well-known object, it is remarkably【C3】mys ______. How many of us know that the "black" box is in fact painted fluorescent orange?
" It was originally called a black box in the days when anything to do with【C4】______(electronic)was new and strange," explains Pete Cook, from a flight recorder manufacturer. "They’re painted orange nowadays to make them more easily【C5】vis______in the event of a crash. "

To take this kind of strain, flight recorders are encased(包装)in two thicknesses of titanium. Memory chips hold the flight data. While FDRs make an electronic record of the plane’s mechanical performance, CVRs record the【C10】com______between the crew. "After a crash in water, they send out a sonar ’ping’ so that they can be found," says Cook. "But they are still only recovered in 80 percent of accidents. " [br] 【C9】
