Quiet blue triangular object blocked the rain before revealing itself to us.About 15 years ago at apx. 2-3 am in the Wichita Mountain Range north of Lawton Oklahoma, while goofing off with friends at a camp site, we all stretched out on the large cement picnic tables around our campsite. It then began to rain. It was odd because I clearly remember hearing the fat drops landing on the ground clutter and foliage around us in a full 360 degrees, however not a drop had fallen on me and none of my friends reacted as if they were getting rained on. Even more bizarre, as we had just been acting foolish and giggling like school girls before the rain came in, all of us had grown completely silent.At this time, it felt as if about 2 to 3 mins had passed, when directly above us where there had been black sky and stars, appeared a large "triangular" shaped object, closer to a Pontiac logo or Star Trek emblem, with "notch" inset on one of the 3 sides. It faintly glowed of a pale blue hue, and I could not make out any fine detail. It seemed to be resting stationary just about 20-30 feet above the clearing in the trees, and as the slab of the camp site occupied about 20 x 20 sq ft. I can only estimate the size of the object to roughly 30-50 ft from the "front" to the tips of the "rear" and about 15-25 ft. from tip to tip on the "rear" What stands out to me the most, is that after about 20-30 secs of processing what I was seeing, at almost the exact same time 3 of us uttered phases that amounted to, "do you...?" "ummm?" and "Anybody else...?". Then, as if it heard us, the object "flew" away. I use quotes there because it was so fast it could have just vanished, but I seem to recall a split second where it seemed to move forward before leaving my sight. At that exact moment we were soaked by the heavy rain we had just been listening to all around us.The object never made a sound. I remember in the silence feeling a kind of calm come over me, and after the event we even discussed how after seeing this this we all sat motionless in silence instead of freaking out at the sight.I am an airforce brat, my father served almost 30 years combined active duty and civil service after retirement, and have lived on or near air fields my whole life. Even today, I literally live less than 2 miles from an airbase. I KNOW AIRCRAFT. this was not ANY type of aircraft I have ever seen.((NUFORC Note: Witness elects to remain totally anonymous; provides little contact information. PD))
