I was shootimg darts in my carport and saw a military helicopter flyer way faster than usual. As it get closer to land i niticed a white light in front of it going at the exact same speed and stayed directly in feont of the chopper. As a veteran and living here in HI I've seen tons of military helicopters and can even hear the rotor difference from inside of the house. I've never seen one fly so fast over the east side and looked like it was chasing the solid white object.
