Large triangular shape craft seen over N.Asheville

Today at about 7:30 (we really did't look at the time) my 6 year old granddaughter and I watched a huge, slow moving triangular cluster of lights or craft flying from Sunset Mountain in the direction of Beaver Lake in North Asheville. I used to fly and I am sure this was not a plane. At first I thought it could be some kind of military experimental craft, but it was too big. There was a lot of wind at the time but we heard a hover sound. Lights were steady and colored and it kept its shape. I understand this is not very scientific, I have no video or pictures. I also understand that it could very well be something else. (Age teaches you to question your senses). Nevertheless, I needed to report what we saw.
