You know the feeling. . . remember the last time you smashed something with your car, or someone smashed you? Or when you know you're going to hit and there's nothing you can do about it but hang on and hope for the best?
Imagine how this guy felt. . . knowing he was going to hit that boulder. . . then knowing he was going to derail. . . then knowing he was going to go sliding down that embankment and go swimming with a 5000HP, 150 ton locomotive up his ass. . . talk about something to have occupational post traumatic stress over. . . the horror.
