Seven people were on board the jet. Biffle, his wife Cristina, his 14-year-old daughter Emma, and his five-year-old son Ryder are among the victims. The other victims were Dennis Dutton, his son, as well as Jack Wadsworth and Craig Wadsworth.
The Cessna C550 crashed just after 10am local time at Statesville Regional Airport north of Charlotte, North Carolina.
Biffle was a Ford stalwart, racing with Roush in all but 11 of his more than 500 starts across a storied 16 years in the NASCAR Cup Series. He became famous for running a stylised #16 throughout his illustrious career.
He won 19 races, started on pole position at the Daytona 500 once, and finished a career-best second in the 2005 NASCAR Cup Series.
Biffle won the second-division NASCAR Busch Series in 2002 and before that the NASCAR Craftsman Truck Series in 2000. He was named one of NASCAR’s greatest 75 drivers in 2023.
RFK Racing hailed Biffle a “cherished member” of its team who helped form a cornerstone of the organisation.

Biffle was a registered pilot, and helped in the relief efforts following Hurricane Helene in 2024.

“On the track, Greg’s talent and tenacity earned him championships in the NASCAR Xfinity Series and NASCAR Craftsman Truck Series, as well as numerous wins and accolades in the NASCAR Cup Series.
“Beyond his racing career, he gave of himself for the betterment of our community. Most notably, Greg spent countless hours of his time helping the citizens of North Carolina during the disasters that followed Hurricane Helene. His tireless work saved lives.
“Our thoughts and deepest condolences go out to Greg’s entire family, friends, and all who were touched by his life.”
