Abstract The object approaches the camera in a steep angle from the ground towards the high flying drone above it. The speed cannot be estimated precisely by referring to covered ground. However, the common blurred line that the object leaves in more than only the last single frame indicates a supersonic speed comparable to the other cases of supersonic objects that pass the drones closely.
