One millisecond of software. Two thousand flights. The CEO is staying. The passengers got a sandwich coupon.

Air traffic chaos traced to software defect lasting a single millisecond

Nats said a software defect lasting "the space of a millisecond" corrupted data in the system managing UK airspace on 8 September, forcing restrictions that cancelled over 2,000 flights and stranded hundreds of thousands of passengers, some sleeping on airport floors. The fault appeared at 10am but was only treated as serious two and a half hours later; the system was restarted after 3:15pm and restrictions lifted at 7:30pm. Chief executive Martin Rolfe refused to resign, calling the defect "very, very obscure", while Airlines UK demanded compensation and passengers learned they likely qualify for none.
