The area it went into a vertical climb was where the USAAF from Nebraska were stationed in WW2. A coincidence but true.At the time and date as stated above I was in my garden and my eyes were drawn towards the tree line about 1500 meters to the rear of my garden. Highly intense lights were shining towards me. The color of the lights were of a silver hue.What was shining those lights at first I could not see. It was a beautiful morning with no clouds in the sky and a temperature of approx 28 degrees. There was no engine noises or other noise distractions in the wooded area. What was shining those highly intense lights at first I could not see. After approx 3 minutes the lights immediately went out and it was then I observed a cigar shape moving from South to North in an immediate 90 degree movement at a speed of approx 20 mph. It kept its trajectory horizontal to the earth. Each 100 meters it would drop 20 meters and move 100 meters at the lower level and then retain its upper level. It traveled Northwards for approx 5000 meters then rose vertically and I observed the saucer shape in full.
