With the Federal Aviation Administration's Notice To all Air Missions, or NOTAM, system back up and running, staffing remains high and systems monitoring is at an urgently high level this morning, a senior official told ABC News Thursday.

Computer traffic on the NOTAM system is at super-high levels as airlines, pilots and airports start the day with normal flight operations while also trying to make up for delays and cancellations yesterday. At the same time, public and media computer traffic on the NOTAM system is running high because of global interest in the antiquated system that crashed on Wednesday.
The ground stop order that paused all airplane domestic departures and the FAA systems failures Wednesday morning appear to have been the result of a mistake that occurred during routine scheduled systems maintenance, according to a senior official briefed on the internal review.
An engineer "replaced one file with another," the official said, not realizing the mistake was being made. As the systems began showing problems and ultimately failed, FAA staff feverishly tried to figure out what had gone wrong. The engineer who made the error did not realize what had happened.
