The Twetos agreed to film the series to boost the career of their aspiring-actress daughter, 23-year-old Ariel, who is studying communications at Chapman University in California and hopes to one day host a show of her own.
A former Unalakleet and East High School athlete, Ariel became a fan favorite in appearances on the ABC obstacle-course game show "Wipeout." (Look her up on YouTube.) A friend working on that show later traveled to Alaska and began pitching a series about Tweto's family to networks, she said.
After a few false starts, Discovery bit, she said.
Her sister Ayla, 24, is training to be a paramedic in Anchorage but visited Unalakleet on weekends and also appears in the show. Another sister, 21-year-old Elaine, spent the fall in London. Both are pilots.
Ferno's parents started an air-taxi company in Unalakleet, where Jim -- a former boat builder whose off-airport landings are featured on the series -- worked as a pilot.
"I used to load his planes," Ferno said.
