Left my house to go meet some friends to go play pool when I saw off in the distance these 3 light that made up a triangle formation. I was driving on the highway trying to get a good view of this but was hard since I was on the highway. This thing whatever it was, was huge ..the formation it was in was at least a mile across. I knew right away this wasn't a plane this thing had 3 lights on the front and the lights were so far spaced apart that theres no way it could've been a conventional aircraft. I do live near an airforce base and I see the C-130's flying in all the time but their light formation on the C-130's is much different. I knew it was something other than a C-130. The amount of sky it took up was just amazing. This object was huge. Eventually lost sight of it when I drove further down the highway.
