I was living in Dumas, Texas and working the evening shift in Amarillo at one of the hospitals. Dumas is approximately 48 miles north of Amarillo. It was about 11:30pm, I was driving home from work, and all of a sudden I heard this loud humming sound. When I looked up almost right above me about the length of a football field there was this very large green glowing cigar shaped object. It had what looked like windows in it but I could not see inside the object. It hovered there for approximately 10 minutes then all of a sudden took off like a rocket and was gone from sight. This was just the beginning of my ordeal with UFO's. I have never told anyone about any of my encounters because I figured they would think I was crazy so was excited when I learned about your organization on the history channel. I am sending another report.
