Think of it as Burning Man for flying enthusiasts. Here, you can almost smell freedom, independence and the sense that anything is possible mixing in the air with aviation fuel.

The formal name for the gathering is the EAA AirVentures Oshkosh fly-in. It features daily airshows displaying everything from acrobats and wing walkers to jet-powered biplanes and the latest commercial and military aircraft.

There will be 500,000 people walking around the Wittman Regional Airport in Oshkosh, Wisconsin, this week—including 10,000 pilots who fly in their planes here— checking out the homemade airplanes and camping under the wings, under the stars. We spent a day with them.

On Monday, the Hawaii Mars dumped 7,200 gallons of water it scooped up from nearby Lake Winnebago on the main runway in front of a stunned crowd.

The show is also replete with workshops teaching people how to build their own planes. A few years ago, some flew their finished product at the end of the show. GE’s Jeff Beam is building a Piper plane like this one in his garage in Kansas. Many pilots who fly here arrive in planes they built themselves.

There’s even a night airshow featuring daring pilots with fireworks attached to their planes’ wings. Beat that, Burning Man! GE is sponsoring the night airshow on Wednesday. Pilot and photographer Adam Senatori captured this image last year. Image credit: Adam Senatori for GE Reports

Big companies such as Boeing, GE and Textron come here, too, to show off their latest planes and engines. Textron unveiled the Cessna Denali here Monday. The plane uses GE’s advanced turboprop engine, which will have 3D-printed parts inside. Image credit: Textron Aviation

World War II pilot Paul Poberezny, who founded the airshow in his basement in Milwaukee in 1953, was born to a poor Midwest family, but “ended up being a millionaire because I have a million friends,” he told AVweb, a news site for pilots. “We’re a family. The early members would bring their kids and later on we’d see the kids come and they’d be married, then years later those kids would come with their grandkids.”

Poberezny could be talking about GE Aviation executive Brad Mottier, who first flew in as a teenager with his father and arrived this year in his yellow Aviat Husky, or Jeff Beam, a GE Aviation engineer who flew his own biplane here and is learning to build his next plane, a Piper, at this year’s event.

Poberezny died three years ago, but his wealth obviously lives on. GE Reports is here this week, also, and we are sharing highlights on Periscope, GE’s Snapchat account and this site. We brought you a day at Oshkosh in pictures.
