A few years back we pointed you toward the world's "best" paper airplane, and while we couldn't entirely back up the "best" claim, this Sky King paper aeroplane is a legitimate world-record holder. This video shows us how to make it ourselves.
Wired's video demonstrates the build from start to finish, but if you'd prefer a more barebones schematic, head over to the Wired page for a nice step-by-step in images. It doesn't look all that impressive when Wired put the plane into flight, but it looks more like a matter of an unbalanced build than a flaw with the design.
If you give it a try, let's hear if you fared better in the comments.
