Federal investigators are headed to Chicago's O'Hare Airport Wednesday to investigate the increased number of air traffic control errors in the past year.
A report from the Federal Aviation Administration showed the number of errors rose because of new air traffic controllers directing planes, failing to keep the proper distance between aircrafts.
There are 52 veterans training 15 controllers with some experience, the Chicago Tribune reports. More training is being done to field added flights and plan for the retirement of veteran controllers.
O'Hare's errors increased to 17 from six the previous year, according to the Tribune. Two of the errors were considered "serious."
The FAA will look into the safety concerns behind the errors today. The administration says the mistakes reflect a national trend.
