Age ain't nothing but a number for Dorothy Hoffner, a 104-year-old woman who aims to become the oldest certified skydiver.

Hoffner recently completed a tandem skydive in Ottawa just southwest of Chicago on Sunday afternoon (Oct. 1), reports WLS-TV.

She left her walker behind just before boarding the plane and got assistance making it up the steps to join the others who would be making the dive with her.

"It was wonderful," said Hoffner to ABC 7 Chicago. "I had to keep myself awake so I could see the scenery." After touching ground, she apparently told a cheering crowd "Age is just a number."

Skydive Chicago, the centre that helped Hoffner make her latest leap in the sky, is working to get Guinness World Records to certify the jump.

The current record for the oldest skydiver was set last May by 103-year-old Linnéa Ingegärd Larsson from Sweden, according to The Associated Press.

Hoffner isn't new to this either, she first skydived at 100 years old although back then she "had to be pushed" out of the plane.

Meanwhile, on Sunday, she reportedly led the jump from 13,500 feet and proved that it's never too late to skydive or do something you love.
