I was sitting in the backyard and looked up at an airplane flying ne overhead. to the right of the plane i noticed what looked like a satellite traveling in a straight trajectory from s to ne. i spotted it about 35 degrees above the horizon and it stopped in its trajectory directly overhead. it darted around for five to ten minutes, sometimes vanishing and reappearing nearby in the sky. i noticed another identical object (small white light) traveling a similar path toward the darting object. when it neared the darting object, both suddenly vanished and did not reappear.
