Investigators were looking for clues Monday into the private jet crash that killed Philadelphia Inquirer and Yankees minority owner Lewis Katz and six others near Boston.
Burnt seats were visible from inside the charred jet, a twisted landing gear lay nearby and other debris were also scattered in a gulley past the runway at Hanscom Field.
The NTSB said it would set up a crane with a basket to dig through the aircraft.
They are also looking at weather, the medical records of the crew and the position of the plane’s flaps.
Investigators have the aircraft maintenance and flight crew training records, and found the cockpit voice recorder and flight data recorder shortly after 6 p.m.
The Bedford Police released 911 calls from the plane crash.
“It looked like an atomic bomb went off,” said one caller. “It was a mushroom cloud.”
James McDowell, 51, of Georgetown, Delaware, was identified as the pilot, and Teresa Ann Benhoff, 48, of Easton, Maryland, was also named as a crew member.
Three others from New Jersey were also killed. Anne Leeds, 74, was a retired preschool teacher from Longport.
Marcella Dalsey, 59, was from Haddonfield and is the executive director of the Drew A. Katz Foundation.
Susan Asbell, 68, was from Cherry Hill, and on a Boys & Girls Club planning committe in Camden County, according to the Inquirer.
