i was returning home one evening when i exited my truck i heard a low humming noise. i looked up and above me about 100 ft off the ground was this object. i wanted to get a camera but i knew that my battery was dead in the camera so i decided to observe the object and try to remember all that i saw. as i looked at the object it began to move slowly approximately 5-10 mph. the object was three octagonal objects connected in a row. each was thirty feet in diameter and was emitting a light from inside lighting up the surface as like you could see through it. not transparent but a light tan skin-like surface. each octagonal surface was outlined to the center to each point of the octagon. no markings or writing on the surface. the object slowly moved above me for about 300 ft, then went to a point i could only see as it moved off to about 1/4 mile away and then acended to about 1500 ft and faced me so i could see all three objects. the objects then seperated slowly to about 100ft apart. the objects then departed at an incredible rate of speed. the two end ones went horizontal away form the center one. the center one went straght up out of sight in a matter of one to two seconds. the sky was clear at the time of the sighting and no fog. i do not know what the object was and i have never seen anything anywhere like it. i don't take drugs or drink. i am not crazy and i am educated.
