Three very bright lights appeared suddenly, silently and hovered

We (two bus loads of conference attendees) were watching the show around 9 PM (right when it got dark) and 3 bright lights (luminescent like nothing i have seen in the sky, much brighter) appeared out of nowhere moved horizontally to the right and just hovered silently, it did drop suddenly again at one point maybe 20 feet. It's hard to tell how long it was but the lights all appeared to be connected to one object, like oval shaped. It possibly could have been 30' long and was less than a mile away and was not far from the ground. It was definitely not a drone (too big, too quick, too silent) it was not a meteor. It was nothing like any of us have seen before. It hovered almost like it was watching the show (and us)(fake gunfire, flames, bright lights etc were going on). It hovered for a few moments and then zipped off as quickly as it had appeared (blurred lights)
The show was going on so it possibly could have been making noise that we didn't hear, but no way it was a plane, too low to the ground.
One member of my party said they saw planes near it. I saw lights off to the side but was too transfixed on the object trying to figure out if it was part of the show and going to come closer and land in the theater.
Couldn't take a picture as flash is not allowed in the theater and it just had turned dark. There were 4 of us from my home State that I know saw it. Probably other attendees saw it too although most might have been looking down at the show. We didn't say anything to anyone but talked about with each other for hours after and the next day so it was noteworthy and unusual….. Possibly UAP?
