fighter jets with unknown objecti was outside on a chair smoking a cigarette with my girlfriend right next to me. we suddenly heard what sounded like a bi-plane, cessna, or a similar single engine aircraft. there was no build-up of sound it wasjust suddenly right there. it sounded like the plane was flying in a circle right above us for some time. at least 3 to 4 mins we heard it clear as day. then the sound dissapeared. just like that. it didnt really click in to our heads until about 2 mins after the sound dissapeared when we heard a low rumble. it came closer and closer. i knew it was fighter jets. suddenly my attention was all about the sky. i jumped out of my chair, went to the middle of my back yard, looked up and i could see 2 fighter jets (about 20,000 to 40,000 feet up), one on either side of something that i have never seen before in my life. it had a large orange circular light in front, a very long oval shaped orange light in the middle, and another circular light in the back. this object had no blinking lights at all like you would see on an airplane. i watched it until it went beyond sight behind the trees.
