Questions Remain About Philadelphia Amtrak Crash

The investigation into the Amtrak derailment in Philadelphia, which killed at least seven people and injured more than 200, enters its second full day Thursday. According to the NTSB, Amtrak Regional Train 188 was hurtling at twice the posted speed limit for the sharp curve where it derailed. The engineer, Brandon Bostian, reportedly slammed on the brakes at the last minute, but the train only slowed to 102 mph before the crash. Bostian's lawyer, Robert Goggin, told ABC News that Bostian does not remember the crash saying, "The next thing he recalls is being thrown around, coming to, finding his bag, getting his cell phone and dialing 911."
