An air traffic control system failure that sparked widespread travel chaos earlier this month was caused by a software defect, the UK's National Air Traffic Services (Nats) has said.
The failure led to more than 2,000 flights being cancelled and hundreds of thousands of passengers affected, with some sleeping on airport floors or getting stuck overseas.
Flights in and out of the UK's main airports were affected, including Heathrow, Gatwick, Luton and Glasgow.
The government had previously ruled out a cyber attack, and last week the Ministry of Defence denied a report that a military aircraft was to blame.
