Flights at New Jersey's Newark Airport have been grounded on Wednesday due to staffing issues.
A ground stop was briefly ordered then a ground delay was put in effect until 10:59 p.m. ET, according to the Federal Aviation Administration.
The FAA's Air Traffic Control System Command Center said due to staffing problems at the travel hub, a traffic management program has been put in place for arriving flights causing delays by an average of 27 minutes.
'If daily or per-shift staffing levels are low, the FAA ensures safety by implementing traffic management initiatives, such as slowing the flow of aircraft into an airport,' the FAA told DailyMail.com.
Delays have been assigned to departures within 1000 nautical miles of the airport and includes all contiguous US departures.
