OREANDA-NEWS US Secretary of Transportation Sean Duffy said that the US authorities may completely close the country's airspace due to the threat to flight safety due to the ongoing shutdown. He said this in an interview with CNBC.

Duffy clarified that the shutdown threatens to close US airspace. Therefore, if necessary, Washington decided to completely close the airspace.

"We will not allow people to travel… We are not at this point yet, there are only significant delays," the minister said.

Earlier, Duffy said that against the background of the shutdown in the United States, there was a shortage of air traffic controllers. According to him, American dispatchers have not been paid salaries for several weeks, and they began to look for alternative ways to earn money.
