论文摘要
天文学家最近的一份报告关于乌克兰（Arxiv：2208.11215）中未识别的空中现象（UAP）的一份报告表明，3-12米大小的深色幻影对象，以高达10-12 km的距离以15 km/s的速度移动，最高为10-12 km。我表明，与周围空气的这种物体的摩擦会产生明亮的光学火球。将其推断的距离降低十倍，完全与炮弹的尺寸和速度完全一致。
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.
