No one on the ground was injured, and no buildings were damaged, patrol Lt. Tony Bradshaw said. It was too early to tell what caused the crash. The National Weather Service said there was no severe weather in the area at the time.
The Lions Club of Fremont on Sunday held a fly-in breakfast, inviting nearby pilots to fly to the airport and display their planes.
After the event, Damschroder offered visitors a chance to go up in planes for the cost of fuel, according to a poster at the airport. The joyrides were not related to the Lions Club event.
It wasn't clear whether those on board had taken Damschroder up on his offer. Also killed were Bill Anstead, 62; Allison Anstead, 23; Daniel Gerwin, 31; and Emily Gerwin, 4; and Matt Clearman, 25.
Federal investigators were on their way to the crash site, Bradshaw said.
Damschroder served in the state House from 1973 to 1983 as a Republican. His son, Rex Damschroder, later served the same seat from 1995 to 2003.
