Ottawa, Ill. (AP) – A 104-year-old Chicago woman is hoping to be certified as the oldest person to ever skydive after leaving her walker on the ground and making a tandem jump in northern Illinois.

“Age is just a number,” Dorothy Hoffner told a cheering crowd moments after touching the ground Sunday at Skydive Chicago in Ottawa, about 85 miles (140 kilometers) southwest of Chicago, the Chicago Tribune reported.

The Guinness World Record for oldest skydiver was set in May 2022 by 103-year-old Linnéa Ingegärd Larsson from Sweden. But Skydive Chicago is working to have Guinness World Records certify Hoffner’s jump as a record, WLS-TV reported.

Hoffner first skydived when she was 100. On Sunday, she left her walker behind just short of the plane, a Skyvan, and was helped up the steps to join the others waiting inside to skydive.

“Let’s go, let’s go, Geronimo!” Hoffner said after she was finally seated.
