Fatal Crashes at EAA AirVenture Spark Safety Scrutiny

A series of fatal accidents during and around EAA AirVenture Oshkosh has renewed concerns about the operational risks inherent in the world's largest air show. Most recently, a Lancair Super ES crashed into a soybean field approximately two miles south of Wittman Regional Airport, killing both occupants — identified as Sean Tommervik and James Sullivan. A preliminary NTSB report indicates the aircraft was flying the Fisk arrival when the pilot was instructed to widen a turn to accommodate two faster jets, after which the aircraft descended into the field and was destroyed by a post-impact fire.

A Pattern of Fatalities

The crash follows a devastating Saturday during the 2023 convention that produced four fatalities across separate incidents. A North American T-6 Texan went down in Lake Winnebago, killing two people, while a mid-air collision between a Rotorway 162F helicopter and an ELA Eclipse 10 gyrocopter claimed two additional lives near the south end of the flightline. Other related accidents that year included a fatal crash in Kenosha County and a non-fatal emergency landing in Marquette County, both involving pilots en route to the event.

Operational Complexity

Safety analysts point to the unique environment at Wittman Regional as a key contributor to the elevated risk profile. The high volume of mixed traffic — ranging from slow gyrocopters to high-performance homebuilts and military jets — creates an exceptionally demanding workload for pilots and controllers alike. While the FAA and NTSB investigate each event individually, the recurring nature of these accidents underscores the broader challenge of safely managing an aviation gathering of this scale and diversity.
