Among the many exhibits are a WWII German U-505 submarine, an Apollo 8 Commando Module (the first manned spacecraft to orbit the moon), a Boeing, a WWII British Spitfire and a replica of the plane used by the Wright Brothers for their first flight.
Another transportation related exhibit is the Zephyr train, which in 1934 smashed the speed record by traveling from Chicago to Denver at an average speed of 124.9 km/h (77.6 mi/h). This shaved more than 12 hours off the previous record. Another train related exhibit is the 'Great Train Story', a model railroad that recreates the journey between Chicago and Seattle.
