Paper airplanes aren't just the domain of bored middle school students.

These high school students in Japan made an airplane that somehow flew back to them after they let it fly out of a window more than one story up.

Yeah, forget all the talk about how the Japanese make better cars than Americans. They make better planes. Heck, they make better planes than the rest of humanity.

The builders of this particular paper airplane didn't do anything different when it came to constructing it, so this was either A) a well-timed stunt; B) a miracle; or C) some act of deception that no one has yet caught on to yet.

If anything, this was probably the smoothest round trip flight recorded in human history. Someone at Continental really ought to figure out how to make this happen for actual planes.
