BOZEMAN, Mont. -

Summit Aviation let its newest pilots take off from Bozeman Yellowstone on Friday morning. They got to fly for the first time, unassisted to Driggs, Idaho.

This group of pilots has something special bonding them together.

Cassie King was wearing her Superman shirt for good luck before she hopped into a four-seater plane Friday. But she was not a passenger, she was the pilot.

"It's one of those things that you always kind of think about but never really expect to happen," said King.

She and the three others spent the whole week preparing for for Friday's big flight in a special kind of flight class. All four pilots aren't your typical flight students -- they're cancer survivors and part of the Big Sky program for kids with cancer.

They learned to fly as part of the newly-formed Pilot Program run by Eagle Mount and Summit Aviation.

King was just 12 when she had several surgeries to remove a brain tumor. It's something Jason Epp has also been through.

For Ashley Thostenson, "I had Hodgkins lymphoma when I was 13," she said.

Morgan Johnson was also young when he was diagnosed. "I got childhood Leukemia when I was 11," said Johnson.

All four said learning to operate the planes was an incredible experience. They said the program has been about more than just flying -- it's changed their lives.

"It's always been a big dream of mine to fly and to be able to get up in the air," said Epp.

King said she's blessed to have this new adventure with her Big Sky family.

"It's really just been incredible," said King. "The generosity of these pilots to let us take up their time. They're so generous, so patient with us and just the memories of this experience is overwhelming."
