A cyberattack on Collins Aerospace disrupted operations at major European airports

A cyber attack on Collins Aerospace disrupted check-in and boarding systems at major European airports, with Heathrow, Brussels, and Berlin most affected. The outage forced several airports to switch to manual procedures, causing long queues and widespread delays, and thousands of passengers were left stranded or waiting for hours.

Collins Aerospace said the issue impacted its Muse software, and RTX described the impact as limited to electronic check-in and baggage drop, which could be mitigated with manual procedures. The incident began on Friday night, and aviation data provider Cirium noted that at Heathrow, Berlin, and Brussels a total of 29 departures and arrivals had been cancelled so far, against a scheduled 651, 226, and 228 departures respectively.

According to Reuters, the European Commission said there were no indications of a widespread or severe attack and that the origin of the incident was still under investigation. The report highlights how reliance on a single supplier can create a single point of failure across multiple sites.
