cd2hsv | how do trains derail? | Recently I saw a video I'm ready. Train conductor texting while training and resulted in the train derailing. How does something like that happen play it's not like you can crash to train with something else like a car, you don't steer it do you?

381s70 | why does the u.s. navy have fighter jets? | Why doesn't the navy give the jets to the Air Force? Or why does it even buy them in the first place? Wouldn't it make more sense to keep all of the planes under the Air Force's control, and all the boats under the Navy's control, instead of dividing them? | explainlikeimfive | http://www.reddit.com/r/explainlikeimfive/comments/381s70/eli5_why_does_the_us_navy_have_fighter_jets/ | {
