30 white lights (satellites ?) travelling in a line disappearing into the sky at same point, no sound, 90 seconds

On the morning of Tuesday March 24, 2020 at 0540 in the morning I let my dogs out to go to the bathroom. I usually accompany them, as my puppy won’t go unless I do. My usual stance is to look into the sky at the stars, usually seeing the little dipper. While doing so this morning I thought it was odd that there were so many stars visible, when I noticed some of them were moving and moving at an accelerated pace. I at first thought they might be satellites, but they were moving too quickly for that and there were too many of them. I continued watching and to my amazement there were approximately 30 white dots, off in the distance, moving from the southwest to the east in a line, following each other. Most of them were equally spaced, but a few were off either to the right or left and then there was one that was trailing and looked like it was trying to catch up. There were no clouds in the sky and they all seemed to disappear at the exact spot in the sky. All! of this took place in a matter of about a 90 seconds
