Flying object change directions
In mid December 2014 my wife and I were vacationing in Cuba. Around 10pm we went for a walk on the beach. As we walked and talked I looked up into the night sky and saw what I assumed was and aircraft. It was traveling in a westward direction when it suddenly made a 180 degree turn. It was not a gradual turn, it changed direction by 180 degrees in the blink of an eye. After watching it for a couple minutes the object vanished. It didn't speed away. It just disappeared.
