  A recent report by astronomers about Unidentified Aerial Phenomena (UAP) in
Ukraine (arXiv:2208.11215) suggests dark phantom objects of size 3-12 meters,
moving at speeds of up to 15 km/s at a distance of up to 10-12 km with no
optical emission. I show that the friction of such objects with the surrounding
air would have generated a bright optical fireball. Reducing their inferred
distance by a factor of ten is fully consistent with the size and speed of
artillery shells.
