Red lights, low humming, central Nevada, two witnesses I was working in the Sage-Steppe desert for four months, on a wildlife study. Our base camp was about half way between Eureka and Carlin Nevada on Rte 278. Middle of nowhere. I had the evening off, and decided to start a camp fire shortly after dark. I had just opened a beer and was playing my guitar when the red lights showed up.Before I start my description I have to say that my recollection of this sighting is hazy, it happened over a year ago, and even a few days later I could not remember details. What I remember is a very low pitched, quiet hum. That is what go my attention. I looked behind me, and two glowing red lights were hovering near by. I set down my guitar and stood up, walking toward the lights to see better. I noticed another set behind them. I could not see the outline of any object, only the lights, but the way they were moving, it seemed that they were connected. They were moving strangely, as if the objects were long and flat and turning from a horizontal position to a vertical position. It took me a minute to realize the red lights were connected and the object was enormous.At some point one set of lights came close, or at least it seemed close due to the scale of the object. I would say it was at least 50 meters in diameter. I do not remember the object leaving. That is the strangest part.I was sitting at the campfire, and was not going to tell any of my coworkers (they were small minded) when they came back from the field. One of my co-workers, who I had a good rapport with came to the fire and stood there with me for a few minutes before saying "I just saw a ufo". I nearly pissed I was so excited.He described red lights, but in a different, more stereotypical "ufo"; configuration. More like spinning red lights.((NUFORC Note: Witness indicates that the date of the sighting is approximate. PD))
