Black Triangle Sighting in Liberty, Missouri on 2020-07-18 23:15:00 – Three white lights moving at very high speed surrounded by dim glow

I live on a common flight path for kc international and kc downtown airport and also mosby regional airport and am used to seeing all sorts of aircraft at various altitudes and speeds. as i sat on my front step sat. night i looked up and saw three very bright lights in a more or less triangular pattern coming from the west at a high rate of speed. as i watched there seemed to be a soft glow surrounding them and a brief amber/orange emmision. my first thought due to the excessive speed and the brief flame or burn off was that it must be military and was hitting the after burner. (not an uncommon sight around here). this thing was moving so fast that it was out of sight almost instantly! i waited and expected to hear a roar from the afterburner or at least something from the jet engine. this thing made no sound at all. i have never seen anything move so fast. the event lasted less than 2 seconds and it was gone. i know this is not much but maybe it can help verify another report. if you have anything to add i would like to hear it
