Black Triangle Sighting in Kansas on 2017-06-25 00:00:00 - I thought it was a b-2 bomber but it had winglets and a sharper triangle shape and was silent

My daughter and i were driving through town (lawrence, kansas) around 5 oclock in the evening and were sitting at a stop light facing north. i was watching swallows flying and then noticed what i thought was a bird moving very slowly. i realized it was not a bird and at first thought it was a b-2 bomber. it was flying sw at an unknown altitude but either it was large enough or low enough that i could make out detail so as the light turned green we pulled into a parking lot and got out and watched it. it continued flying sw and then banked due south. as it turned i could make out it's shape better. it was a sharper point in the front than a b-2 bomber and it had winglets. it banked again due west and flew out of sight. it was completely silent. i took two pictures with my iphone but of course they don't show much. my daughter and i have both seen b-2s often as they are based in missouri and have flown over lawrence several times. they are loud and more rounded than this was.
