Two separate aircraft accidents left a total of four people dead and two injured this weekend in Wisconsin, officials said.
The first crash occurred when a single-engine North American T-6 aircraft crashed into Lake Winnebago on Saturday around 9 a.m. local time, according to a press release from the Experimental Aircraft Association.
"There were two occupants in the plane, a T-6 Texan, and recovery efforts for the deceased occupants and also the plane began shortly afterward," the EAA said in the release.
Later Saturday, two aircraft collided in midair at the Wittman Regional Airport.
The aircraft belonged to individuals attending the Experimental Aircraft Association’s annual fly-in convention in Oshkosh, but they were not involved in the air show, a statement from the organization said.
The press release, citing the Winnebago County Sheriff’s Office, said two people were killed and two were injured. The injured were taken to a local hospital and were in stable condition.
The aircraft involved in the second crash were a Rotorway 162F helicopter and an ELA 10 Eclipse gyrocopter, according to the press release.
The airport halted operations while the accident was investigated. The air show began after a short delay.
The Winnebago County Sheriff’s Office has not yet released the name of the deceased individuals pending notification of family members.
