May 19 (UPI) -- The Federal Aviation Administration on Monday is investigating after another outage at the Philadelphia air traffic control center responsible for handling flights at Newark Liberty International Airport.
The FAA said the control center lost radio frequencies for two seconds at around 11:35 a.m. EDT.
All aircraft "remained safely separated," the FAA said in a statement to CBS News.
The FAA told Fox News that Philadelphia TRACON Area C "lost radio frequencies." This is the same control area that has encountered other problems.
