This reminds me of something I saw that I never really talked about. Maybe about 7 years ago, I was out bicycling at around 10pm at night outside of Socorro NM (a small desert college town), and to the west I saw a light appear from behind some mountains steadily heading up and north in a slightly curved path. I thought it was a plane or a helicopter until it suddenly disappeared after about 30 seconds. I assumed it turned off its lights or that I somehow misunderstood what I saw, but a minute later, a new light appeared from the same original spot, followed the path again, and disappeared. This sequence repeated maybe ten times. I assume it was some kind of missile test that I saw. The White Sands Missile Range was 10+ miles to the southeast (the wrong direction), though I think I remember there also being other explosive testing ranges nearby to the west. I would love to know what exactly I saw, though I never knew how to go about finding that out even if the information was published somewhere.
