Bus sized drone in NWA?

Bus sized drone in NWA?
Time: Sunday night, at 6:37p
Location: Springdale/Fayetteville, AR

I saw a bus-sized drone thing in the sky when I was about to exit highway 71. It was insanely large with 6-8 lights on it, as it was long and symmetrical. I have a picture, but it is not clear at all… as it grew closer, I was in awe, as it was so low compared to a regular plane or Walmart Delivery Drone. It was LARGE. And it went right over me. I did not get a picture, as I was on he highway and I truly thought the picture I captured earlier was enough. 

Is this a govt drone? Has any one else seen this before??? I’ve seen multiple drone sightings too, but this one was just odd. 

Before anyone tells me it was a plane (commercial or private) it was not. I live near a private strip where my friends used to fly, and this was nothing near resembling a plane. I hope the picture does not make it come off as so.
