More than 10.3 thousand flights were delayed and more than 1.4 thousand were canceled in the United States, among other things, in a national ban on their departure due to a failure in communication systems, below from the FlightAware data portal. Such a ban on leaving the United States is introduced only for the third time in history (after attacks of September 11, 2001 and the failure of the crew alert system in January 2023). @rusyerevantoday.
