Children . Documentary
 

Maddie is out and about exploring different ways to travel. She visits an airfield and uses a special camera to find out how the rotor works to help make a helicopter fly. An animation shows how changing the angle of the rotor blades makes the helicopter go forwards and backwards. Next, Maddie visits a workshop to see how a tricycle is constructed from a big box of parts and to see how the tricycle can be adapted to suit a user's needs.
