Observed black triangular object with lights at points heades SSE at treetop level.

Black triangular object traveling SSE across US 291 south of 23rd st.  Object made no noise.  Travelled at close to 60 mph (est) which seemed slow for an airplane, but thought could be "Stealth Bomber" since Richards-Gebauer Airbase was in KC.  This made no sense though, since AB is way south and west of this location.  AB does not base the B-2.  They were later deployed to Whiteman AFB.  I have seen and heard the B-2 since then, and can tell you that what I saw was not that.  I would estimate size as roughly front to back 50 ft side to side 150 ft. No blinking strobe, no navigation lights. I experienced no electrical disturbance, no time loss.
