Doug Hansen, 64, and Tina Hansen, 55, were killed in the crash, according to their funeral notices from Furness Funeral Home of Clark. Arrangements are pending.

Grant Rix was attending the Groton Fly-in/Drive-In with his family Sunday and said he witnessed the crash.

“We were walking our kids to the vehicle to leave, and the plane had already taken off and was just kind of going along the runway at about 10 feet off the ground or something like that, trying to gain airspeed,” Rix said.

At first, he said, he thought the airplane was performing a barrel roll, so he pointed it out to his kids.

“All of a sudden it looked like the airplane didn’t have much altitude, and then it hit the ground with the wheels down then flipped over onto its backside,” Rix said.

That was around 11 a.m. at the Groton Municipal Airport.

The plane was a 1997 American Champion 8KCAB fixed-wing, single-engine aircraft, according to information from the Federal Aviation Administration. It was registered to Doug Hansen.

The plane crashed under unknown circumstances near the runway, also according to FFA information.
