Metallic egg shaped hovered behind resort and untill right of mountain, lasting 2-5 minutes.Came into to view all of a sudden. Was metallic egg shape as had reflection from the sun on the left side of craft. Was in view behind resort we were at then continued to hover beside right of mountain until it was out of view. Lasted approximately 2-5 minutes.We were on vacation at a resort outside Vieux Fort, St. Lucia. I saw the craft first then told my friend. She saw the object when it was passing by the mountain. I did not get any photos or video as was in awe ad it happened so quickly.There is an international airport in Vieux Fort.I believe there is a US military base near by.
