4 lights speeding very fast across sky silently

I saw my own UAP (formally UFO) in the Seventies on the farm.  My then husband and I saw 4 lights, brighter than stars, in a perfect square in the night sky.  Suddenly they zoomed across the sky overhead without a sound, and so fast that they left light streaks in a wavy pattern.  No plane goes that fast..It was 4 separate objects as lights.  I reported it earlier this year because it has haunted me ever since.  It was silent in a very quiet place in rural PA.
