I was driving on I-70 west toward Kansas Cit,y around 730 pm on 9/19/15, when i first saw them. i just remember the sun was going down and i was driving toward this beautiful sunset, as i watched these lights appear and they faded as the horizon changed colors and turned dark. i actually sped up because i wanted to see what they were and it looked like one of the lights was moving to the right toward the direction i was driving to which was into downtown. there were two bright lights that appeared circular one brighter than the other which was the one the was moving right toward where i was going. the other two lights are harder to explain because at first i thought they were those clouds that the airplanes make but as i drove closer and watched they didnt fade but seemed to get brighter. these 2 werent circular but kind of a swish shape, was very odd. these four lights hung in the sky sort of in a square formation as the brightest circle moved toward what se! emed to be over downtown. i then saw a PLANE !!like one of those small ones, fly between me and these lights and then fly back and back again before it dissapeared. i have never seen a plane to that in my life! i was in shock, took my phone out which is very dangerous while driving but i wanted to record this but i couldnt do it while i was driving. i was looking at every person driving beside me to see if they were seeing this but the couple people i saw didnt seem to notice this!!? wtf. it all was very bizzare. then the lights began to fade and by the time i reached the westside it was pretty much dark and i could only see one of the lights which then faded or i lost view of it from behind buildings.
