3 objects flying in erratic motion high in sky observed from my 3rd floor east southeast window facing window. After observing for several minutes, called a co-worker to help identify. Neither of us can explain what we first thought were birds but erratic flight, altitude, and a reflection from sun discredited the thought. Though many military jets frequent the sky, none would fly with such patterns so close. After viewing for some time, the objects just disappeared into a cloudy sky.
