Air traffic returned to Miami International Airport on Friday, after the US Federal Aviation Administration lifted the ban on flights across the country, following a malfunction in the communication systems of air traffic control centers.
The suspension of flights caused chaos and confusion at American airports, and marked the longest suspension of air traffic across the country since the attacks of September 11, 2001.
According to the data of the "Radar Flight 24" website, more than 6,600 flights were canceled, while approximately 8,600 more flights were delayed, in addition to the cancellation of 1,500 flights scheduled for Sunday.
Aviation sector analysts warned that a nationwide shutdown of flights for four hours could disrupt airline schedules for several days, given the difficulty in redistributing affected planes, crews and flights.
