the object moving erratically lasting for approximately 10 seconds near airport I work in the aviation business in Louisville, KY. On February 7, 2009, I was on ramp #1 of SDF airport watching the sunrise from my vehicle. It was around 7:40 in the morning. As the sun rose above the horizon, it quickly ascended into the blanket of clouds reaching beyond me. I proceeded to drive away, then I remembered I needed to go pick up some paperwork. I immediately turned back around and drove past where I was parked. After I drove for quarter of mile I was facing the security entrance which faces the southeast. As I was driving, I something caught my eye just above the security entrance below the blanket of clouds. I said to myself "I have never seen a cloud that round before". The round object stayed there for five to ten seconds and then it went up into the blanket of clouds. I saw a shadow of the object moving erratically lasting for approximately 10 seconds. The shadow then disappeared. The conditions of the day were mostly cloudy. The ceiling was 3100 feet, winds were 18 mph from the Southwest and wind gust 26 mph. Temperature was 54 degrees and visibility of 10 miles.
