Very funny BVR shot. You can see the target drone plume at the rear and also the smoke trail of the so called BVR missile while it is engaging the drone. Most likely it was a WVR shot for the spectators seated below and fired from a distance no more than 2-2.5kms from the drone and that too from exact rear of the drone.First ever JF-17 BVR test against a target drone, in February 2018.
