String of dozens of solid lights

High altitude string of non-blinking yellow lights viewed in eastern sky traveling north. Most were evenly spaced apart. Looked like a very long string of military formation planes but way too fast, lasting way too long, no blinking lights and so many it would have to be some sort of massive movement larger than I’ve ever seen outside of the history channel for a world war. Giant tracer rounds would make sense if they were not so precisely traveling straight across the same path at the same speed across the entire skyline without changing color speed or drifting.
