The NTSB said the investigation into what caused the crash that killed NASCAR legend Greg Biffle may be lengthy but the plane's black box has been recovered.

Cathy Grossu, the mother-in-law of retired NASCAR driver Greg Biffle, said she had seen the family a day before the fatal crash.

President Donald Trump on Friday remembered former NASCAR star Greg Biffle as a "great young man" after he and his family members were among the seven killed in a plane crash.
