On Sunday night flying in the Northeast was a mess. Flights out of the three DC-area airports were paused while the FAA’s air traffic control organization suffered an equipment failure at Potomac TRACON. Flights resumed shortly after 7 p.m. Eastern time, but there was a backlog to clear. Some flights cancelled, for instance as crew exceeded their maximum duty hours.
Royal Air Maroc flies Washington Dulles to Casablanca five days a week using a Boeing 787-8. After several hours staff hadn’t communicated at all with passengers. Then they finally cancelled the flight. And the passengers went into revolt. Staff fled for their safety.
