Flying too closely

摘要

AMERICA'S AIRCRAFT-SAFETY regulator has been the industry's gold standard since it was set up in the 1950s. When the Federal Aviation Administration (FAA) called out an aeroplane as unsafe, counterparts around the world followed its lead. That changed after a Boeing 737 max jetliner crashed in Ethiopia on March 10th, killing all 157 on board, five months after the same model went down in Indonesia in apparently similar circumstances. The FAA grounded it only once all other big regulators around the world had done so.
