What happened in a residential area north of new york city last night turned into a mass casualty event. And its a huge warning about what can happen anywhere vehicles encounter Railroad Crossings in this country. This was a commuter train on the metronorth line out of new york. It hit an suv on the tracks in valhalla new york. The resulting flash fire consumed much of the first car and seemed to fuse the suv to the front of the train. The death toll stands at six including the driver now confirmed to be a mother of three. Its the third busiest rail line in the nation. The ntsb is there on the scene as is our own tom costello tonight. Tom, good evening. Reporter hi brian. Good evening. Just moments ago they moved the burned out carcas of that train just further down the train tracks just a little bit out of view. Meanwhile, the medical examiners now going through Family Dental records to try to identify those victims who didnt make it out of the train alive. The First Arriving fire and ems units found a scene of carnage, twisted wreckage fire and smoke. And passengers climbing through windows desperate to escape a burning train. All units, more ambulances are required for a car versus train Motor Vehicle accident. Reporter it happened at 6 30 p. M. Packed rail line that serves commuter towns. Two cars went billowing out from everywhere. Reporter witnesses say an suv was sitting very near the track when the train crossing arm came down on the car. The driver, a mother of three, got out to check for damage then inched forward right into the path of an oncoming train, exploding on impact. As the train carrying the suv 1,000 feet down the tracks the electrified third rail was ripped free tearing into the first train car. Passenger chris gross was inside. Came up about a foot away from my face. After that happened people are screaming, crying. Weve got one possibly trapped in the train, possibly alive. Ive got doa in the train as well. Multiple injuries. Reporter in all six people were killed including the driver of the suv. 15 people injured, some seriously. Lacerations, contusions crush injuries open fractures, dislocations smoke inhalation and flame burn injuries. Reporter through the day the suv remained embedded in the front of the train as ntsb investigators arrived on the scene. Witnesses told police the driver may have been stuck in traffic trapped on the track when the train approached. She turns, walks, gets back in the car, light hesitation and then moves forward and at that instant the train hit. Reporter piecing together how the accident happened will be part of the ntsb investigation. Was there any indication that the crossing arms were not working properly . At this point we have no indication to believe that they were doing anything other than operating properly. Reporter tonight, the dead include the suv driver 49yearold ellen brody, 53yearold eric vandercar, a father of two, and 69 walter lipke, a cue rater at the metropolitan of art. One accident killed four people just over a year ago. Tonight, ntsb investigators are anxious to talk ot conductor and engineer. Brian. Tom costello at the scene of that crash for us tonight. Tom, thanks. Now to the other major disaster were covering. A commercial airliner crash in taiwan that was incredibly caught on dash cam video the whole way down. At least 31 people were killed when the transasia air ways turbo twin engine prop went down. A dozen missing and feared dead. Rescuers were able to save 15 people from the wreckage. We get the latest tonight from nbcs ian williams. Reporter the dramatic final moments captured by the dash cams of passing cars. The transasia twin prop plane clipping an elevated roadway before slamming into the river below. 58 passengers and crew trapped in the fuselage upsidedown and half under water. Rescuers rush to the scene. A young child among the first of more than a dozen pulled to safety. A massive operation painstakingly extracting survivors as an anxious crowd gathered on the river bank. Survivors were rushed to local hospitals. On the elevated roadway, debris where the plane hit. And a battered taxi the same one that can be seen just ahead in this dash cam video. The driver and passenger stunned but alive. The video shows the plane narrowly missing nearby apartment buildings. Fueling speculation that the pilot deliberately swerved to avoid them. The plane went down just two minutes after taking off from taipeis songsha airport. The pilots reported distress call. Engine flame out he said suggesting possible engine trouble. The propellers you can see this one is spinning at a faster speed than this one. You can see all four blades here. And theyre almost stopped or much slower than this one. This indicates that this engine is producing power while this one may very well not be producing power. Reporter the cause should be known soon. The black boxes have already been recovered. Tonight, the battered fuselage was lifted from the river as the search continues for the missing with the death toll almost certain to rise. Ian williams nbc news beijing. Jordan today continued to vow revenge after the world witnessed the horror of isis burning a jordanian military pilot alive. Theyve already taken revenge with executions and threats of increased air strikes lending credence to this idea that isis has pushed this months long conflict to a critical turning point now. Our report on that tonight from our chief Foreign Affairs correspondent andrea mitchell. Reporter jordan is boiling over demanding revenge. A country united in outrage by the horrifying isis video rallying behind. I stand in support for every jordanian. Reporter so far the video is backfiring causing revulsion in much of the arab world, including the west bank except in raqqa. Amateur video shows people cheering as they watched the video of the pilots torturous fiery death. Projected like an outdoor movie on the wall of a building vowing a tough response that would shake the earth. King abdullah ordered the execution at dawn today of two convicted terrorists on death row including the wouldbe suicide bomber the woman isis had demanded betraded for the jordanian pilot. Jordan Intelligence Services confirm what they had suspected, their pilot had been long dead burned alive in early january. What kind of steps is jordan likely to take . There is no question that this is going to intensify jordans participation in the coalition against isis. Reporter that means more air strikes. But a Key Coalition member the united United Arab Emirates stopped flying combat missions in december after jordans pilot was captured complaining angerly that the pentagon didnt have search and rescue teams nearby. Of special concern to the uae, many of their fighter jets are being flown by women like major mariam now grounded while her government demand more pentagon support. In fact the jordanian pilot death has exposed long simmering anger by arab leaders who say the white house is not permitting enough fire power to completing its goal of defeating and degrading isis.

In Dickson County texas, paid a ransom after computers with important case files were paralyzed. You dont want to contribute to a criminal enterprise by paying a ransom but at the same time we had to weigh that versus the fact we have a community that we support and serve. Reporter but many experts say dont pay. If none of us pay the ransom these guys would go out of business. Reporter goss didnt pay since there was no guarantee to get her stuff back. You had to make the choice to say goodbye to all those important documents. Thats right. I had to think really hard what are in those files.
