Biffle, his wife and two children were among seven killed when Biffle’s private jet crashed and exploded into flames while trying to land at a North Carolina airport Thursday morning. The Cessna C500 went down at Statesville Regional Airport, which is frequented by NASCAR teams and Fortune 500 companies, just before 10:30 a.m., according to the Federal Aviation Administration. Footage shot by WSOC-TV captured the aircraft entirely engulfed in flames as emergency crews rushed onto the runway. nypost.com
