Easter eggs near KLSE?

[mesaba 116 10]

I flew the Mississippi River Valley between KPDC and KLSE. As I approached La Crosse, I saw 5 objects that appeared to be moving in formation. They looked to be at about the right airspeed to be aircraft, but there was no identifying text with them, and they all travelled the same path. (Maybe KLSE is near an AI zone border, where AI is generated??) But why no text? Any ideas what I was witnessing? And no, I hand't been drinking from the "World's Largest six-pack" at the House of Heilman (obscure SW Wisconsin reference).

I encountered and screencapped a similar phenomenon. I later determined it was a contrail being viewed from a strange angle.

Problably UFOS, some were reported near KLSE. No abduction reports yet. Wouldn't be too worried. ;-)
