EAA AirVenture Oshkosh is the World’s Greatest Aviation Celebration. In 2021, the event was back after organizers were forced to cancel the show in 2020 due to safety concerns. For 10 days, from Saturday July 24 to Monday August 2, Wittman Regional Airport (KOSH) was once again transformed into the busiest airport in the world. The statistics are almost incomprehensible. More than 10 000 aircraft flew in to the area with 16 378 takeoffs and landings being conducted at KOSH. 5000 volunteers spent more than 250 000 hours preparing and maintaining the grounds to allow 608 000 visitors to enjoy the event, the third highest attendance in the show’s 51 year history. Weather conditions, including thunderstorms, hail and tornadoes, added to the already challenging set of circumstances organizers overcame to make the event a success.
