The co-owner of the Philadelphia Inquirer newspaper, Lewis Katz, was killed along with six other people in a fiery plane crash in Massachusetts, just days after reaching a deal that many hoped would end months of infighting at the newspaper and help restore it to its former glory.

The 72-year-old businessman's Gulfstream corporate jet ran off the end of a runway, plunged down an embankment and erupted in flames during a takeoff attempt Saturday night at Hanscom Field outside Boston, authorities said. There were no survivors.

Katz was returning to New Jersey from a gathering at the home of Pulitzer Prize-winning historian Doris Kearns Goodwin. Also killed was Katz's next-door neighbor, Anne Leeds, a 74-year-old retired preschool teacher he had invited to accompany him.

The identities of the other victims weren't immediately released.
