An FAA computer outage caused flights to be grounded nationwide for hours on Wednesday. There are calls for an investigation into the cause of the incident, and the FAA has announced it will conduct a thorough review.
The problems with the notice to air mission system, which alerts pilots to current conditions and potential safety issues on their route, started on Tuesday afternoon and continued overnight. The FAA says the cause may have been caused by a damaged database file.
