NEWARK, N.J. - Federal investigators say the co-pilot of a Learjet that crashed at New Jersey's Teterboro Airport in May 2017 wasn't authorized to fly the plane.
The jet crashed into office buildings and a parking lot just short of the runway as it prepared to land. Both the captain and co-pilot were killed.
The National Transportation Safety Board said Tuesday the plane's captain violated company procedure by allowing the co-pilot to fly. Investigators also say the crew made numerous mistakes during the short flight from Philadelphia.
