USS Burton Island (AG-88) и USS Edisto (AG-89) в Антарктиде

Operation Highjump was a naval task force organized by the United States Navy in 1946-47 and led by Rear Admiral Richard E. Byrd. The mission of the task force was to establish a scientific research base in Antarctica and conduct exploratory missions in the area. The task force was composed of over 4,000 personnel and 13 ships, including an aircraft carrier, and was one of the largest expeditions to Antarctica in history. The operation was controversial, with some suggesting that it was a military operation disguised as a scientific research mission. However, the official reason for the expedition was to explore and map the area, as well as to study the geology, biology, and meteorology of Antarctica. Operation Windmill was the United States Navy's Second Antarctica Developments Project, an exploration and training mission to Antarctica in 1947–1948. This operation was a follow-up to the First Antarctica Development Project known as Operation Highjump. While there is no evidence to suggest that Operation Highjump or Operation Windmill had any connection to Nazis or UFOs, there is a conspiracy theory that claims exactly that.
