Objects would fade in and out, changing altitude, speed and direction.

I am an overnight delivery driver and for the past 3 mornings in a row I have seen multiple orb/star like objects appearing and disappearing over the NE sky from my location (Would put objects over Central MO). The objects appear from between 2am and 4am and will appear to "dance" around the sky, changing altitude, direction and traveling at insane speeds.
The first morning I witnessed 4 of the objects together, the second morning two, and this morning I seen 3, however I was only able to get a partial picture of two of the objects before they faded away.
The objects do not appear to have any lights similar to that of aircraft also flying in the sky, as you can see airplanes in the sky with their flashing beacons where as these objects are a solid color that fades in and out as they move.
I did check multiple flight radars to see if there was a group of aircraft in or around the area where they might be flying, but nothing was found.
The fact it has occured 3 mornings in a row, either tells me its the government testing some secret aircraft near Whiteman Air Force Base, or the objects are indeed UFOs.
