It was the second time in 15 months that a glitch in the flight plan system caused delays. The FAA said in a statement that it is having a problem processing flight plan information. 'We are investigating the cause of the problem,' the agency said. 'We are processing flight plans manually and expect some delays. We have radar coverage and communications with planes.'"
