Was on the upper decks of the Carnival Horizon when I noticed an object following the ship. It was below the clouds and behind the ship. Suddenly the object shot above the clouds to about the same hight as a commercial plane and changed into a glowing disk which began zigzagging in completely different directions at speeds Ive never seen. I grew up In Colorado between the Air Force Academy and Bukley Air Force base and saw many types of military planes at high speeds but never have I ever seen anything like this. This definitely wasn’t a plane/drone and was silent. We were midway between Jamaica and the Cayman Islands just south of Cuba. I caught the glowing disk on camera but because of lighting I can’t see it but It can be filtered. I shortened the video to where the object was a glowing disk above us zigzagging. It was eerily following our ship and once it got to close it dipped out.
