EAA AirVenture 2021 opened to enthusiastic crowds July 26, following the cancellation of last year's event due to the COVID-19 pandemic. Now, the show is back at Wittman Regional Airport in Oshkosh, Wisconsin, with thousands of aircraft, campers and attendees, displays of warbirds, home builts, vintage aircraft and aircraft of all types, day and nighttime air shows, educational sessions and more. This year's AirVenture highlights aircraft involved in humanitarian missions, such as the Orbis Flying Eye Hospital and aircraft involved in delivering COVID-19 vaccinations.
