After eating thanksgiving supper several relatives and I were outside of my mother-inlaws house talking ,when I noticed an airplane flying east ,then I noticed a blue object ,about the size of a dim star well above the plane dropping at a slight angle away from the plane ,maybe slightly faster than the plane was traveling, and when the blue object got even with the plane it made a 90 degree turn and started following the plane, it was only a few hundred feet behind the plane when the blue light went out. It happend so fast I didn't have time to get anyone else to look. the whole thing only lasted about 12 to 15 seconds.I was quite excited. this was my third ufo to see in my 50 years.
