After an electrical problem took out the runway lights at Tulsa International Airport Tuesday, they went down again Thursday.
Daniel Meier, a spokesmen for TIA, said that the lights were down for about ten minutes Thursday due to the same malfunction they had Tuesday.
He said they were able to override and bypass the malfunction to get the lights on again.
According to Meier, the monitoring system is new and the first one didn't work right Tuesday. He said a replacement part was installed, tested and worked properly during Thursday afternoon but failed at night.
Meier said he wasn't aware of any diversions but had a couple of delays that lasted about 15 minutes.
They said they had a staff member on site in case of a malfunction.
