UFO Sighting in Greensboro, North Carolina on 2019-04-18 22:30:00 – Mystery silent lights- not my first time viewing them

On at least 1 other time some months back, i witnessed this thing from my front door (the antenna is over to the right a few hundred feet). same silent, fast oddly flying deal as before- but this time, there wasn't a tiny blue light between the 'legs' of this thing. the way the lights are on it, it looks like a flying coffee table. it usually flies like a helicopter- at an angle, straight as an arrow, and fast. except... there's not a *hint* of sound. everything on the video clip is road noise, and maybe from that cessna flying overhead. it flew right over me, and i could hear it just fine- plus me, grumbling about the lousy focus on a supposedly $1000 phone.. this thing- much faster, and *nada*. when it shot past me when i was on the doorstep some months back- not so much as a whisper. i will try to get closer, somewhat better footage (after seeing this performance from the phone... ha!) what can i say... it's unidentified, it's flying, and it's an object. :/
