The incident happened on Monday...
An exchange between Air Traffic Control and pilots from Ryanair and Aer Lingus has been released after a near miss between the two flights.
A Ryanair flight (RYR966V) from Venice to Ireland and an Aer Lingus flight (EIN43R) from Milan passed very close to each other in Irish airspace.
At their closest, the two aircraft were just under one mile apart laterally and 700 feet vertically.
The absolute minimum is three miles laterally and 1000 feet vertically in busy airspace like Dublin.
The courses were quickly corrected but it's unclear who was at fault in the video, but it's currently being investigated.

You may have heard this Air Traffic controller at Dublin Airport expertly handling a narky British Airways pilot.
