The programmable Lego brick which is at the heart of these robotics sets has undergone several updates and redesigns, with the latest being called the 'EV3' brick, being sold under the name of Lego Mindstorms EV3. The set includes sensors that detect touch, light, sound and ultrasonic waves, with several others being sold separately, including an RFID reader.
The airport handles an average of more than two million passengers a year, and millions of pounds of cargo. The airport's main runway can handle airliners as large as the Boeing 747, although most passengers arrive on smaller aeroplanes, such as ATR-42s, Boeing 737s and Boeing 757s. Boeing 747 activity at this airport is almost exclusively limited to cargo flights.
Bag 6 starts the airport terminal. Like most CITY builds, they are meant for play so it's really only half a building. It includes one minifigure and the revolving door entrance. While the entrance is cool looking, it's about twice the height of a minifigure and there isn't enough physical space for one actually to fit through the door. I'm not a fan of the design.
