I was outside smoking, looked up and saw what i thought was a satellite, then right behind it there was another object, after they cleared the trees in my yard i saw the 3rd, one in the lead and 2 following in a triangular shapex silent. then roughly 8 seconds later i spotted another one, on the same path. it was a bit overcast to the south and west, the direction they were flying from, very spooky. they just kept coming, i stood there for about 20 mins watching them pass overhead. i'd estimate maybe 25 passed, then i went outfront and they were still flying over. waited inside for about 5 mins, then went outback again, they were still flying over. being dark, it was hard to tell how high up they were. they were about the size of stars, no flashing lights or sound. i guess about 2 miles up and about a mile or so spacing. anyways, i stood out back for another 4-7 mins and saw the same triangular rear detail and i did at the beginning of the covoy, as i am calling it. what the heck was this!???!!
