I recieved a call to go to Alert Status. I was active Air Force as a Weapons Tech. I was trained in Nuclear and Stategic Muntions and delivery. I was trained in TAC but was Transfered to SAC after my return from SEA(South East Asia).I was called to Alert Status, which means I must leave my domicile (in Brilmey) and proceed to my duty station at Kinchloe AFB.I took the back roads to achieve better time. This short cut took me through farmland, in the middle of no subdivisions or close homes.As I proceeded down this road I came across a saucer shaped object in the farm field. It hovered below tree top level. 30 feet or so off the ground. I stopped my vehicle and watched the Craft. It made no noise and was silver metallic. It was no aircraft that I was trained to recognize. I stopped my vehicle and got partically out the car. I had one foot in and one foot out the vehicle. I watched the craft. It was dark as you could be imagined at 3-4 am in the morning in the northeran latitudes. I flashed my vehicle lights off then on. The craft turned a cowling light that shone to the ground, on then off. I repeated the same process, the hovering craft did the same. I waited several minutes. Then looking off to my right I notice two more craft just past a tree line perpendicular to me lifting off the ground beyond the tree line. There where three craft total. As the other two craft climbed to tree top level I realized that I could stay no longer as I would be AWOL if not there with in the time limit of Alert status.Very few people know of this.
