Flying west to east, very fast, close lights in shape of a wide V. then disappeared, then a few seconds later another set, loose wide V

12:07am Kansas, Southern sky 10-15 white lights close together making a wide V shape. But slightly irregular V shape. (almost like this shape { )They were flying from west to east, looked to be high up, and flying very fast, the sky was clear and the moon was waning 3/4 full. Then they disappeared and shortly, maybe 3 seconds later another grouping of lights followed in another wide V shape but slightly diffrent in shape. They followed the first set but a bit further south, then also quickly disappeared into the sky flying east..about 4 minutes later we saw the same V shape but looked to be higher in the sky, flying east to west, the lights were brighter and closer together. My husband also saw all 3 incidents.
