Went out to watch space station pass overhead and smoke. while looking up and seeing what appeared to be a satelite, i noticed several what i though were odd placed stars, then realized they were moving objects from west to east and exactly spaced apart. approx 5 visible at a time. after seeing about 6, i started yelling for my brother and he came out with his girlfriend and son. my father also came out and seen some. while my brother was watching about the 8th to 10th following same path, he noticed one from east traveling west to same exact point in the sky. we also then looked all directions and eventually seen 3 more come from southwest in a ne direction to the same spot. i live near bwi airport all my life. know planes, know paths, these were way higher in elevation. i doubt satelites travelt the exact path at exact intervals. i also am an electrician who worked at the airport for years on runway lights etc... i know planes. spot in the sky would be towards the north from me and when the objects reached the approx area looking up at the ladle of the big dipper, the just vanished!! i would say i seen 12-14 travel exact path west to east, 1 from east to west, and 3 from se to ne, and again, all went to same spot in sky and vanished!!
