At the Boeing Museum of Flight in Seattle, there is a full size mockup of an F/A-18 fighter. A ramp allows visitors to climb into the cockpit and get a sense of what the pilot sees and feels.  

A guide at the top of the ramp points out the various controls and gauges in the cockpit and gives information about the aircraft's capabilities to each visitor who gets in.  

When my two-year-old son sat down in the plane, he seemed fascinated by all he saw and heard. Then, he looked out at us and said, "Gramma, could I have a quarter?"
