Shocking 15 satellite like objects flying in the night sky in pattern one after another.

Multiple UFO sighting in Sioux City, IA.
 My girlfriend and I counted approximately 15 satellite like objects flying one after another across the night sky on March 20, 2020.
 Objects were flying in the same direction spaced apart in equal distances.  Only 2 or 3 were visible at a time.  They all appeared at the same point in the sky.  They also disappeared at the same point in the sky.  Each object was visible for about 20 second or so.  I would say they looked to be just seconds behind one another.
 Objects were flying in the exact same path in the same direction.  Other commercial planes where flying by which gave a great comparison to how much higher in the sky the ufo objects were.
 I have never seen anything like this. I have seen satellites that look similar but never so many one after another after another.
