Temperature, Humidity Won't Sink This U-boat

摘要

More than a half-century has passed since the German U-505 submarine was captured during World War II, but the curators at the Museum of Science and Industry in Chicago strive to keep the sub looking in fighting shape. Since the U-boat's capture in 1944, it has survived a near sinking, a treacherous tow from the Atlantic to the Great Lakes, and 50 years of bitter Chicago weather in its post as an outdoor exhibit at the museum.rnIn 1997, the museum began a restoration project designed to preserve the U-505 and move it indoors to a climate-controlled environment. Presently, the submarine resides on a specially constructed 75 × 42 ft underground exhibit space at the Museum of Science and Industry. To preserve the U-Boat's external and internal structure, the exhibit space was engineered for the most precise temperature and humidity control.
