A large ship hovering over a warehouse

It was large with a material that made it hard to see (when lights flashed on it, it seemed to drown or swallow light - it's hard to explain), rectangular shaped but not perfect. It had a flimsy pole that waved back and forward but stood straight up when the light on the tip of it came on. A friend and I tried to record it, but it didn't show on our cameras because it was at night and hard to see with our plain eye sight. We we're about 80 yards away and didn't hear anything coming from it. Which is amazing because how massive it was. After hovering for about 10mins it slowly pulled off and then disappeared. It was larger than a commercial airplane. Again, it was rectangular shaped but had different curves do to what looks like it's boosters and other things I can't describe.
