About 15 years ago at my parents home in Southwest Virginia, I saw some weird lights flying fast at very low level below the mountain ridgeline at night with a Huey in hot pursuit. Being interested in aviation history and knowing quite a bit bout military aircraft and UAVs/drones, I can safely say that these lights were neither.
Good recent book on the subject:

I’ve seen multiple objects I was never able to ID as conventional aircraft or spacecraft. One incident I observed a dim, pin point, star like object which appeared to move behind the lunar limb and did not appear to exit. Spooky did not begin to describe this incident, which lasted only about 5 seconds.
