Dual lights traveling together in irregular patternlooking into the Milky Way we noticed 2 lights with space between them but seemed to be fixed together(possibly a football field apart). we noticed it moving relatively slowly(small airplane speed and about the same hieght as a small airplane would travel) and it turned toward us (we could see the lights brighten). Moving at the same pace it turned away and then looked to travel upward(as the lights got closer together and dimmer). It kept traveling into the milky way until we couldn't see it anymore. We never heard sound at any time. The lights were white (like headlights of a car) and did not change color.
