Overview

• The outage began overnight from Friday to Saturday after a cyberattack on Collins Aerospace’s MUSE platform disabled automated check-in and bag-drop at airports including Brussels, Berlin, Heathrow and Dublin.
• Airports reverted to manual procedures, causing long queues, dozens of cancellations and hundreds of delays, with operational data pointing to Brussels and Berlin as the most affected.
• Eurocontrol directed airlines to cancel about half of scheduled departures from Brussels from early Sept. 20 through at least early Sept. 21, later extending the restriction window.
• Collins and parent RTX said the disruption was limited to electronic check-in and baggage drop and could be handled manually, and aviation safety and air-traffic services were unchanged.
• EU bodies and national cyber units opened investigations with attribution still unresolved, as Italy’s CNAIPIC reported no compromise to core systems and kept a high state of alert.
