Why US Airlines Are Panicking Over Trump’s New Aircraft Threat

US President Donald Trump has taken to social media to threaten sanctions on the Canadian aerospace industry. According to the BBC, Trump posted online that he would be “decertifying (…) all aircraft made in Canada” and imposing a 50% tariff on planes made in the country. The threats come as Trump accuses his country’s northern neighbors of “wrongfully, illegally, and steadfastly” not certifying US-builtGulfstream aircraft.
