With huge delays of 30 minutes into Dublin, pilots and controllers were doing their best to clear the backlog.
Aerlingus Airbus A320 from Milan flight #EI433 and Ryanair Boeing 737 from Venice Treviso flight #FR9451 came extremely close over Dublin. At their closest, the two aircraft were just under 1 mile apart laterally and 700 feet vertically, the absolute minimum is 3 miles laterally and 1000 feet vertically in busy airspace like Dublin’s.
The controller and pilots quickly corrected the situation It is not clear yet who was at fault All the ATC conversation in relation to this is in the video.
