On april 21, 2012 i was stationed on ft. riley, ks and living in on post housing. i took my two german shepherdâ€™s outside to use the bathroom before going to sleep at around 2140hrs. while sitting on my back porch watching my dogs they both suddenly ran back to me and began barking toward the sky to the east. when i looked up i saw the object slowly flying directly overhead. i was frozen in shock as i realized this was no plane, drone, or helicopter i had ever seen in 14 years of military service. the object made absolutely no sound before, during, or after it flew directly overhead. i observed this object for just over 2 minutes as it was approaching from the east and heading west. way too slow to be a plane. i have never seen anything like it since that night and honestly, i never want to again. the fact this thing was silently flying over a u.S.Army installation with no signs of pursuing crafts or mention of it by anyone in my unit the next day scares me.
