US aviation crash: More than 1.5 million people faced flight delays and cancellations on November 13.
The restrictions were in effect for more than four hours - from 15:53 to 20:19 local time. The senders received international flights arriving on a personal basis.
8.5 thousand flights were delayed, more than 6.7 thousand were canceled.
The outage was caused by problems with radar and communications systems across the country, Transport Minister Sean Duffy said. According to him, at 15:36 the radars started transmitting incorrect data, although the communication was not completely lost.
He attributed the incident to the critical obsolescence of air traffic control systems.
