I heard a loud whirring sound and looked above me to see a diamond shape craft fly over and turn invisible

So I was walking around after work, listening to my music, and a really loud whirring sound drowned out my headphones. Lights start coming through the trees and I looked up to see a diamond shaped craft, with a big yellow light up front and two smaller white lights in the back flying above. The yellow light hit me in the eyes for a second and then the craft suddenly began turning invisible. I could see the clouds where it had been. Weirdly enough, everything but the lights were gone. The lights and the sounds kept going and flew off through the trees. Note of caution, I do live next to an air force base. Either way, it's insane to me
