(NBC News) The National Transportation Safety Board has blamed a deadly 2015 Amtrak crash in Philadelphia on a combination of human error and the lack of fail-safe technology.
The safety agency also says vandalism played an indirect role in the derailment, which claimed eight lives.
The May 12th, 2015 tragedy began when a commuter train was pelted by rocks, setting off a chain of events that led to a deadly error by the engineer of another train, Amtrak Northeast Regional 188.
The investigation by the NTSB found the engineer Brandon Bostian was distracted by radio dispatches about the vandalism and went into a curve at 106 miles an hour, more than 50 miles over the speed limit.
“He went in a matter of seconds from distraction to disaster,” said the NTSB’s Robert Sumwalt.
The locomotive and seven cars hurtled off the tracks, killing eight and injuring more than 200.
