HOW THE *beep* COULD THAT PILOT CRASH THAT HELICOPTER...

...STRAIGHT INTO A MOUNTAIN THAT WAS RIGHT IN FRONT OF HIM?! I'm referring to the train scene where Delroy Lindo's character is shooting at the train. He gets shot in the arm or something while the train is nearing a tunnel. Shortly after that the train goes into the tunnel and the pilot, who DIDN'T get shot or injured, just goes straight into the mountain the train is going through. That part made no sense at all, even less than any of the other less-than-realistic parts of the movie. Seriously, no amount of suspension of belief can explain how an otherwise competent pilot can just crash the helicopter he's flying straight into a wall of rock. I mean, he was able to run the copter's blades over the train to chop down a couple of baddies but couldn't avoid running into a mountain???
