Saw 3 solid lights in the shape of a big triangle, hovering, silently

Driving down the hill from the center of town, on the way to pick up my wife from work at Christopher heights, me and my children saw three solid orange lights in the shape of a big triangle hovering silently in the sky for about 5 seconds then we could not see it any longer. After waiting about 15 minutes for my wife we headed home the same direction we came, again seeing the same lights hovering over the old state school grounds where there are two new rotaries. I pulled into one of the rotaries to stop and look at the craft it was very big was not a helicopter or a plane and had like I said three orange solid lights shaped like a triangle we watched it for about 2 minutes before the lights just went out and disappeared.
