On 2 July 2022, a Boeing 737-800 taxiing for departure from runway 24L at Barcelona under GND control using a route which crossed the runway 24R extended centreline almost immediately following the runway end was abruptly stopped by the controller on the centreline and almost immediately, an Airbus A330-300 departing 24R overflew the 737 at about 700 feet. The 737 should have been stopped at an earlier unlit stopbar position before the A330 was given takeoff clearance. An inadequate lighting control and indicating system was assessed as contributing to procedural failure. Both controllers involved were correctly qualified but very inexperienced.
