Authorities suspect that a tragic plane crash in North Carolina has claimed the lives of retired NASCAR driver Greg Biffle and several of his family members.

The incident involved a business jet that went down on Thursday at a regional airport frequented by NASCAR teams and major corporations, resulting in a significant fire and multiple casualties.

According to flight records, the aircraft was registered to a business owned by Biffle.

Iredell County Sheriff Darren Campbell confirmed the presence of fatalities but refrained from specifying the number of victims.

The Federal Aviation Administration reported that the Cessna C550 crashed during its landing at Statesville Regional Airport, located approximately 45 miles north of Charlotte.

Golfers playing next to the airport were shocked as they witnessed the disaster, even dropping to the ground at the Lakewood Golf Club while the plane was overhead. The ninth hole was covered with debris.

“We were like, ‘Oh my gosh! That’s way too low,’” said Joshua Green of Mooresville. “It was scary.”

The National Transportation Safety Board and the FAA were investigating. AccuWeather says there was some drizzle and clouds at the time of the crash.

The plane took off from the airport shortly after 10 a.m. but then returned and was attempting to land there, according to tracking data posted by FlightAware.com.

The plane had planned to fly later from Sarasota, Florida, to Treasure Cay International Airport in the Bahamas before returning to Fort Lauderdale, Florida, and then to Statesville by evening, data showed.

Video from WSOC-TV showed first responders rushing onto the runway as flames burned near scattered wreckage from the plane.

The airport’s website states that it offers corporate aviation facilities for Fortune 500 companies and several NASCAR teams.
