We were traveling south on a country road and i looked out and noticed a weird looking craft in the air so we pulled over. as soon as we stopped and got out, my friend then noticed that there were actually 3 of them. they appeared to be floating approximately 200 ft or so above us. they seemed only large enough to carry only one individual. there were no blades or other propellors to indicate they were anything other than off world or if from earth, they used a technology that we were unfamiliar with. they made zero noise and traveled directly over our heads. they were white and it looked as if there was some kind of skeletal framework surrounding the outside of the crafts. we gave chase but quickly lost them as they blended into the sky background. my cellphone would not focus on the crafts or i would've had a great photo. i've never heard of single passenger ufos and was curious if there have been any other sightings such as this?
