My sister, judy jett and i were traveling south from nashville on a secondary street, mt.Juliet rd. i glanced to my right and saw a huge vehicle hovering about 500 ft. in the air. i pointed it out. it looked like a giant caplet or tic-tac,just hovering. she stopped i got out of the car to take a picture. it took me about 3 seconds to lift my phone and it was gone. totally gone, the sky was clear, but it was gone.
