Listen to the MP3 and fill in the blanks. This week’s 1 foreshadows (预示) the end of that golden age. Another MAX 8 crashed in October in Indonesia in 2 . Although investigators have yet to determine the cause of the Ethiopian Airlines accident, regulators suspect that the max 8 has a design flaw. This plays into the worry that a new technological phase is under way. Aircraft are becoming 3 , as computers take charge. This promises 4 flying, but the interaction between human pilots and machines is still 5 . In the Indonesian crash the pilots fought a losing battle against anti-stalling (防失速) software that forced the plane’s nose down at least 20 times. The industry’s 6 is amplified( 放大 ) by its organisational complexity. In the 1990s a few Western airlines 7 and a handful of regulators had global clout (影响力) . Now there are hundreds of airlines and 8 pilots worldwide. In 2018, for the first time, less than half of the global fleet was based in the West. Maintaining common standards on training and procedures is harder. China and other countries want a bigger say. The 9 of American regulators has slipped because they have let 10 decline. This suggests they are cosy with industry.
