Red/green/white from south to north of entire sky in 6 seconds.

I was laying on my back in my backyard as the twilight was setting in.
I was watching for satellites. I saw a few airplanes already and saw two satellites.
When I saw this "UFO" I could not believe how fast it was going. It was much higher than the very thin cirrus clouds, large enough to see red/green/white. Regular satellites (like Starlink) I have seen take 30 to 50 seconds to go by the sky, and all go NW to SE. Aircraft are very common over Wichita and can be seen pulsing.
What I saw went by so fast I was stunned by the speed that it crossed the sky. It appeared at least 10 times the size of a typical orbital satellite. I remember pointing at where I first saw it and where it was out of sight. It was a 90° arc of the sky from S to N, it zipped through that much of the sky in maybe 4 seconds. There were no streaks behind it, like a meteorite.
I don't recall the exact time but it was near the end of nautical twilight.
I have watched the night sky hundreds of times and seen thousands of satellites and planes, and "shooting stars". I have never seen anything go across the entire sky like this.
