I observed a single light, another several nights after, then two several nights later and another tonight. this is not due to the meteor shower as those move north to south. these traveled the opposite direction and had no arch or tail on them. i have seen many meteors as well as shooting stars. i have seen many civilian planes as well as fighter jets due to being ex military and served overseas. these all moved at an insane rate of speed and in a straight line with no sound. i have seen 5 in total in the last 4 weeks and 4 of the 5 were in the exact same location. the 4 mentioned were all over a tree in our back yard. meaning miles above, but always the same area. i know what i saw and am truly unable to label these as a star, meteor, or man made craft which brings me to label them as nothing other than an unidentified flying object.
