What’s behind the computer glitch that grounded US flights?

Failure of a safety-critical system forced the grounding of all departing planes in the United States for 90 minutes on Wednesday.

Thousands of flights were disrupted – domestic and international – with delays to planes heading to the US from elsewhere.

The Federal Aviation Administration said an initial review traced the fault to a damaged database file.

But there is no evidence of a cyberattack as yet.

So how could this happen – and what lessons can be learned?
