The grounding of all flights and Federal Aviation Administration systems failure that occurred Wednesday morning across the United States was caused by a mistake made by an engineer.
An engineer 'replaced one file with another,' an official told ABC News, not realizing the mistake was being made and ultimately causing the system to show problems and fail.
The culprit engineer has yet to be identified.
Engineers and IT teams are working feverishly to prevent the system from crashing again today, as they also scramble to figure out if there are any similar systems that could fail as easily.
More than 11,300 flights were delayed or canceled on Wednesday in the first national grounding of domestic traffic in about two decades, since 9/11
An official told the outlet, 'It was an honest mistake that cost the country millions.'
