Took my dog outside and instantly noticed lights in the sky.

Saw bright white/red lights on flying object in night sky. Objects were going in same direction, but not exactly in line with one another. I saw 4 at first then more came from same direction. They flown west to east and some made a southern curve and gained altitude and disappeared. Others didn't curve as smoothly and just rose up and disappeared. I live 10 miles from the airport and am familiar with aircraft. These were too quiet for military, too many for commercial, too high for recreational drones, and faster than any Cessna. The lights were brighter on the craft than I've every seen. I'm 53 years old and lived here 20 years. I estimate the crafts were at 4000 to 8000 feet before disappearing higher.
