Children’s eyes light up when they see an actual FedEx cockpit within the museum. Inside they can sit in front of the instrument panel imagining all the places where they can fly. The air traffic control tower is just a skywalk away. Below the cockpit is the package conveyor system where your child can monitor their package being counted and delivered all over the world (Paris to the White House to the North Pole).
For real hands-on experience, they can try keeping the model plane in the air (literally) at the wind tunnel.
