USMC pilot Capt. Dan Holland flying one of three jets with the Third Marine Air Wing on an east heading at Ft. Lauderdale at about 26,000 feet and 400+ mph saw a gleaming white ball-shaped object with a gold ring around the lower 1/3, about 2x size of his jet, descend vertically on a collision course, took evasive action, radioed the other jet pilots to look. Object suddenly stopped 3,000-4,000 feet above, he banked toward it and activated gun camera but object then accelerated and disappeared to the east at tremendous speed in about 15 seconds. The other two pilots flying ahead of him did not see object.
