Crossing the key bridge in the early morning i noticed several cylinder object with what looked like spheres looping around each one. they went up and down, in and out of the clouds. sometimes disappearing and returning. after watching for about 5 min they all went into the clouds. several seconds later one dropped back out of the clouds, came down a couple hundred feet and stopped. at this point i started recording on my phone camera. the object hovers for about 1-2 minuets and then slowly moves off the the right (ne). with the naked eye, i could see the white sphere going beside and around the crate but the video doesn't show it. i also to still images. after watching it for a couple minuets i left to pick up my mother who was visiting from new hampshire. on the way back about 1 hour later we noticed 2 of the 3 crafts however they were much further away. the second time around i did notice something els. i noticed a very large white sphere. i only viewed it for several seconds before it was obstructed by trees.
