The UK Aircraft near-miss reporting agency, the Airprox Board, has recently reported a near-miss incident between a light aircraft and an unknown object over Wellingborough that occurred on 18 Feb 2021.
The report states, "The DA40 pilot reports that they were performing a VFR navigation training flight and were on a leg tracking towards Grafton Underwood.
Just 1NM to the south of Wellingborough town, while performing standard lookout, they spotted the UAV closing fast, to the left and slightly below the nose at a range of about 100m. They performed a steep right-hand climbing turn but, by the time they had begun climbing away, the UAV was already abeam their left wing and slightly below.
The UAV was 1-1.5m across, grey/silver in colour and with no visible markings or lighting. Immediately afterwards they informed Cranfield approach and passed the location of the incident. There was no NOTAM informing of UAV activity in that area active at the time."
The Airprox board conclude "In the Board’s opinion the reported altitude and/or description of the object were such that they were unable to determine the nature of the unknown object."
