Flight tracker information appears to show the helicopter flying into the hill at 150 mph. Looks like the pilot tried to gain altitude right at the end. I do not know how accurate the flight tracker info is. If you listen to the air traffic control tape you can hear the controller asking the pilot what he is doing. He asks what are you intentions? Your altitude is too low for that terrain. The air traffic controller told the pilot to follow the freeway but for some reason the pilot took a left turn into the hill. We'll get a report from the Feds in a few months. Be interested to see what they find.
