Additional flight cancellations are expected through this weekend as airlines gradually recover from a global tech outage that has left thousands of passengers stranded at airports. More than 5,400 flights into, out of, or within the US were canceled Friday and Saturday and more than 21,300 flights were delayed, according to FlightAware.com. A third day of chaos at airports could be in store with more than 600 flights already canceled Sunday morning. The issue extended beyond airports, with businesses, government agencies, health and emergency services, banks, schools and universities around the world grinding to a halt or seeing services disrupted due to a flawed software update for Microsoft Windows operating systems issued by the cybersecurity firm CrowdStrike, experts told CNN. The outage “has basically turned computers into bricks around the world,” Glenn Gerstell, former general counsel of the US National Security Agency, told CNN Saturday. “This is probably going to be the biggest single computer incident in terms of overall effect,” Gerstell said. “Maybe not the number of computers, but the impact on people’s lives.” CrowdStrike CEO George Kurtz apologized to customers and said a fix has been deployed, but experts say getting systems back in order will be a lengthy process.
