It seems like the most dangerous threat to Cathay is the following line from the article: > China’s airline regulator declared it unsafe Based on other sources it means that Cathay would be forbidden to enter China's airspace. It entails much more than not being able to land in China: since the airspace of Hong Kong is surrounded by that of China, it is virtually impossible not to enter China's airspace when using the only international airport in Hong Kong. Being forbidden to enter China's airspace means not being able to fly to and from Hong Kong, a death spell for Cathay.
