A private jet carrying Philadelphia Inquirer co-owner Lewis Katz and six other people ran off the runway and burst into flames at Hanscom Field in Bedford, Massachusetts, on the night of May 31, 2014, killing everyone aboard, according to the National Transportation Safety Board.

The Gulfstream IV had been chartered by Katz for a day trip and was bound for Atlantic City when it began its takeoff roll on runway 11 at about 9:40 p.m. Instead of climbing, the twin-engine jet ran off the end of the pavement, struck approach lights and an antenna, tore through the airport perimeter fence and came to rest in a ravine near the Shawsheen River. Fuel ignited on impact.

Residents near the airfield called emergency dispatchers to report a fireball at the end of the runway. The recording attached here is the dispatch audio from that night.

All seven people on board died. They were Katz, 72; the pilots, James McDowell and Bauke "Mike" de Vries; flight attendant Teresa Anne Benhoff; and three of Katz's friends, Anne Leeds, 74, a retired preschool teacher from Longport, New Jersey; Susan Asbell of Cherry Hill; and Marcella Dalsey, 59, of Williamstown.

Investigators determined the crew had tried to take off with the airplane's gust lock engaged, a system that locks the flight controls in place while the jet is parked. The pilots skipped the required flight-control check that would have caught the problem, the NTSB said. When the captain tried to raise the nose near takeoff speed, the yoke would not move.

The cockpit recorder captured a pilot saying "lock is on" as the jet accelerated, and one of the men saying "I can't stop it" as it ran out of runway, according to the board. Had the crew aborted a few seconds sooner, the report found, the jet could have been stopped on the paved surface.

In its final report, released September 9, 2015, the NTSB blamed the crash on the crew's failure to run the flight-control check and their delayed decision to abort. It found the pilots had skipped complete control checks on nearly all of their recent flights, and faulted Gulfstream's gust-lock interlock design and the Federal Aviation Administration's certification of it. The FAA later ordered gust-lock fixes across the Gulfstream IV fleet, the manufacturer redesigned the system, and families of several victims sued Gulfstream and parts makers.
