My buddies were getting a ride home from a parent after football practice when all in vehicle described different color lights going back and forth in the sky. little lights with one big one. when they told me that, i thought, sure, little green men. this was taking place in 1967 or 1968 and i remember it being in the summer. so the next night, we took our sleeping bags to the elementary school just up the road from us. we were sitting on them talking as kids talk. i was looking up at the clouds with a moon above them and i saw a craft that looked like a 747 without a body to it, just a big shadow below the clouds! i yelled 'look at that '. what a silence! it made no sound, no lights, and seemed to float across the sky almost directly above us. it wasn't that high in the sky! we all (about 6 of us) sat back down trying to figure out what that was. 5 min. later the identical thing went over us in the same place. we ran up the hill to have a closer look and the fear, for better words, overtook us and we ran back down to the school tembling with the excitement of not knowing what we saw. after the incident i checked out books about the germans flying wing and came to the conclusion it was the military checking out the lights that were seen the night before. as i thought about it later in my life, a couple of things still didn't make sense. complete silence and it was traveling so slow, it should have fallen out of the sky!!
