The near-miss is said to have happened on Saturday and was reported by the pilots to the control tower as the plane arrived from Frankfurt. It has been described as the most serious incident involving drones at the airport to date.
The drones were spotted at around 2,950 feet within protected air space when the aircraft had already started its landing procedure.
The pilot saw them almost by accident because at this stage, one of the most critical in the landing process, the crew is usually concerned with the instrumentation,’ said an aviation spokesman.
A search has now been launched for the owner or owners of the three drones but an amateur enthusiast is not suspected.
