A passenger flight on approach to Glasgow Airport was involved in a near-miss with a drone.
The A319 jet, along with passengers and crew, were considered at "high risk" collision after the drone was spotted dangerously nearby.
The aircraft came within 150 feet of the drone, which was being flown above the permitted 400ft height, at midday on February 23 this year.
The white drone with red stripes was spotted passing beneath the jet as the plane made its final approach into Glasgow Airport.
The near-miss was revealed in the last UK Airprox Board (UKAB) monthly report.
The report reads: "The drone was being flown above the maximum permitted height of 400ft such that it was endangering other aircraft at that location."

The Board agreed that the drone was flown "into conflict" with the passenger jet and created a "high" risk of collision.
The report added that the pilot's overall account of the incident suggested that safety had "been much reduced below the norm, to the extent that safety had not been assured".
The incident involving the plane at Glasgow was one of seven near-misses between aircraft and drones across the UK featured in the UKAB's latest monthly report.
There were 125 such incidents reported in 2018, up 34% on the total of 93 during the previous year.
Aviation minister Liz Sugg said: "Drone users who fly their drone over 400 feet without permission are breaking the law.
"The safety of people both in the air and on the ground is paramount, and anyone putting others at risk faces serious penalties up to a life sentence."
