OSHKOSH - As AirVenture rolls along, the airshows continue to be a popular attraction.
However, there is more to the fly-in.
EAA bills itself as the "Spirit of Aviation," but it could also be called the "Spirit of Innovation."
Homebuilt aircraft have long been at the center of AirVenture and the place where many innovations in flight have come from.
"Some ideas are crazy, some won't work, some are absolutely innovative and it's really neat to see different ideas and see what people are thinking," said Randy Awker of Chicago.
Some ideas, like the Terrafugia flying car seemed impossible. But the car made its first flights at AirVenture this year.
"Oshkosh has been a great place for us to come and really get some support and exposure for an idea that really does seem a little bit crazy but has always been really well received," said Terrafugia COO Anna Mracek Dietrich.
Still, some far-fetched ideas have their skeptics.
"I have my doubts about whether it will fly," said William Beard of Chicago of the flying car.
Other ideas like this electric powered plane by Oshkosh-based Sonex Aircraft addresses a more pressing need.
"If you don't see a need for this alternative I don't know what planet you live on. Everybody is talking about green technology and there is only so much fuel in the tank so to speak," said Sonex Aircraft General Manager Mark Schaible.
Also new this year is a new building called the Innovation Pavilion. Parked outside is the first natural gas powered plane. Inside are companies big and small with ideas they hope will improve aviation.
"It's really all about the EAA spirit and EAA movement and community. With EAA being headquartered here and the air show being here is the reason our company is here," said Schaible.
Joining others with their heads in the clouds and hoping their inventions will someday join them.
Terrafugia officials say they already have a waiting list of about 100 people looking to buy the roughly $275,000 flying car.
However both the flying car and the electric powered plane are several years away from being available for general aviation.
