Russian drone hit F-16. But are you sure?

The drone video was made from a daytime camera. The device is moving towards an F-16 standing in a shielded parking position. The movie is simply a short distance away, so the hit leaves no doubt. However, much indicates that it was a mock-up. The main argument behind this is the air intake of the ‘airplane’, which is flat on the top and collapses on the sides at consecutive angles.
