I saw orange lights in the sky last fall that I can't explain. Having served in the U.S. Air Force I am familar with lots of aircraft, and afterburners at night.
What I saw I can't explain. Others in the area saw it as well. It made the local news.
Active bases around the area said they had no activity that particular night.
I've witnessed several inexplicable things in the sky this lifetime, and know for a fact that none of them were natural or man-made.
Although I can't say for a fact exactly what those things were, I do know for a fact that I saw them, and that someone caused them to be there. The only remaining question for me, is who put them there.
