World War II warplanes were often painted with sharp-toothed heads on the fronts, to improve the morale of the pilot’s side and, hopefully, decrease it on the enemy’s. But apparently that’s not enough; now scientists have come up with a justification for stenciling the whole thing to look like a shark. 😉

(All kidding aside, this does sound interesting. And probably looks pretty neat too, when you’re close enough to see it.)
