BEDFORD, Mass. - Data from flight recorders indicate the jet that crashed over the weekend in Massachusetts in which Philadelphia Inquirer co-owner Lewis Katz was killed reached a speed of 165 knots (190 mph) and never lifted off from the runway, according to the National Transportation Safety Board.
NTSB investigator Luke Schiada said Tuesday one of the recovered black boxes also recorded conversations inside the cockpit, but they will be analyzed further before a transcript is released.
The Saturday night crash at Hanscom Field in Bedford, Massachusetts, killed Katz and six others on his private jet.
Schiada said data from the block boxes indicated a rise in brake pressure and the application of thrust reversers before the crash.
Tire marks on the runway also suggest the pilot may have been trying to stop the plane.
Former President Bill Clinton is among a group of dignitaries slated to speak at a memorial service for philanthropist Katz.
The service is being held Wednesday morning at Temple University, Katz' alma mater.
Also on the list of 15 speakers for the service are Governor Tom Corbett, former Governor Ed Rendell, comedian Bill Cosby, New Jersey Senator Cory Booker and Inquirer editor Bill Marimow.
An investigation into the crash is underway.
Katz and three friends were attending an education fundraiser at the home of historian Doris Kearns Goodwin and her husband, Richard Goodwin, an adviser to Presidents John F. Kennedy and Lyndon Johnson.
Doris Kearns Goodwin also is on the speakers' list.
