I observed one nite several objects flying in a kind of oval formation and change to a vee formation. There wasn't any sound.

I am a local truck driver who isn't sure if ufos are real but i will tell you what i saw and let you decide. One nite while hooking up to a trailer at a large chemical factory I saw a large group of lites passing over head. THe lites were flying very close to each other. I thought it was a low flying jetliner with it's landing gear open which would be very unusal for around here. After the lites passed over head all of them changed to a flying Vee formation that is when I knew that all those lites were seperate objects. Also there wasn't any sound. Even with all the noise in the plant there sould have been some sound.
