I was driving in my work truck, north bound on the by pass road (Hastings, NE) by the over pass next to the waste water treatment facility. The craft was a greyish color, the best description of the shape would be similar to a bus. No wings. It appeared as I glanced in that direction. (to the east). When I looked back, it was gone.My estimation is the craft was approximately 200 meters off the ground and within a couple miles. I was shocked, there was another car on the by pass in front of me. I have always wondered if they saw it too. I know this happened a long time ago, I just never thought about reporting it.((NUFORC Note: Witness elects to remain totally anonymous; provides no contact information. PD))
