A 39-year-old air traffic controller who was the sole operator on duty for the Newark Liberty International Airport during a 90-second blackout early this month penned an anonymous column warning travelers against flying out of her own airport.

At one point, the FAA had targeted 77 total arrivals and departures at Newark each hour, but at the start of construction on April 15 they requested airlines cut that down to 70 total during the day and 62 during specific hours in the late afternoons and evenings.

The New Jersey airport, which has faced radar problems and major delays, is scrambling to bring in more air traffic controllers and complete construction.
