World's largest indoor flying Airliner

Due to the helium filled fuselage and an aerodynamic flight control, the airliner displays the same flight characteristics as the original whilst flying slowly and silently through the air. 
The airliner has a 4.8 meter (15.5ft) wingspan and weighs just 350grams (12 ounces).
Ideal as a brand carrier for airlines, airports and for use in large enclosed spaces with a minimum size of around 50x 20 meters / 150 x 60 feet.

The airliner is available for hire with piloting crew and can be branded as required.
