Or it is because the brilliant people at CNN decided to get rid of the previous video, and to replace it with one where they all talk about how wonderful and amazing the paper airplane’s flight was without bothering to actually show the flight. Because when you watch a video about such a thing, it’s not as though you want to actually see anything, right? I’ll have to look around for a better video when I get back from work again.
EDIT: Okay, here is a YouTube video that shows the actual flight. Though it’s less of a flight, really, and more of a 45° downward glide.
