<human>: Tonight, while helping a friend move, I saw a man get hit by a car traveling around 75 mph. The man was on the right hand side of the road, there were two cars on the left hand side that had been in an accident and this man appeared to be trying to get across to help them. Why he thought that he could cross three lanes of traffic is beyond me. He got to about the third lane and realized he was about to be hit, when the impact was made, even for me in another car everything went into slow motion. He flipped through the air about 15- 20 ft. In the air. I did not get a chance to stop, but when I passed by I was going very slow, he looked dead to me, and I see no way that he could have lived. So I do believe that tonight, I witnessed a man get killed. I feel very sorry for the man that got hit, but even worse for the person driving the car that hit him, I cannot begin to imagine what they must have to live with from now on. 

So my question to you is, what is the most terrifying thing you have ever seen?

Can you condense the text into three sentences or less?
<bot>: saw a man get hit by a car. Flew about 15-20 feet in the air. I think he died.
