Gary Mantz and Suzanne Mitchell recount their visit to the MSI in Chicago, a site of world-class exhibits and home to technological marvels. From classic locomotive engines, and a Boeing 727 airliner, to a WWII German U-Boat captured by the U.S. Navy in time to assist with planning the D-Day Invasion.
