To celebrate 100 years of airship flying the Goodyear company sent two of its large format airships to Oshkosh. The airships N1A and N2A are usually referred to as 'Wingfoot One' and 'Wingfoot Two' Together with a third sistership, these were built by ZLT Zeppelin Luftschifftechnik in Friedrichshafen, Germany, around ten years ago. They are used as flying billboard during sportevents and as observation platforms during natural disasters. And they are big, their length is about the same as that of a Boeing 747-8!
