My son and I were in the back yard of our house a little after 1:00 in the morning last night. (about 1:15 am this morning). We had gone outside to get our cat, who was on a ledge outside the second floor window and wouldn't come in or climb down, just kept meowing. We were both looking up at the side of the house wondering how long we would have to wait for her to come down, when two circular white lights flew over the house, going more or less west to east or northeast. they were about the size of a baseball held at arms length. we both saw it. about two minutes later they came back (or two others like it came by) again, from west to east/northeast. this time they both stopped -- don't know how far away -- they seemed close, although the (?) spheres were small. they both stopped for a second or two...as my son and i watched, one of the objects/lights "flew" away at a right angle to its previous path of flight ... not up in the sky, but back to the northwest at what seemed to be the same altitude as before. the other object remained motionless for a few moments (5 seconds maybe) then continued to the northeast on pretty much its original direction. they were definitely two different objects that were flying in tandem at first, then split up. my son and i ran out to the front yard with the video camera, but didn't see anything more. they made no noise. they seemed small but close. if they weren't close they must have been huge. we read in the news that similar sightings were made last night in Waldorf Maryland, about 10 miles from our house. we always thought these things were crazy, but now we know better.((NUFORC Note: Witness elects to remain totally anonymous.
