A giant, fiery mustache makes this already awesome photo that much awesomer

Here ’s something you do n’t see every day : a U.S. Coast Guard C-130J soaring like a shot toward you , set against a backdrop of sundown - illuminated clouds . But that ’s not the only matter noteworthy about this photo . See the gigantic flying mustache/ mephistophelian eyeball star late into your soul from behind the woodworking plane ? Turns out those are n’t eye at all ( or a mustache ) ; they ’re a dramatic instance ofwake turbulenceknown as “ wingtip convolution , ” captured here in absolutely breathless point ( get through hereto see it in high - res ) .

FYFD explains :

Wingtip vortices form on plane due to the finite length of their wings . In worldwide , lift on the wings result from low - pressure , gamy - velocity melodic phrase move over the top of the wing and high - pressure , scurvy - speed strain make a motion below the wing . Near the wingtips , the high - pressure air is able to slip around the border to the top of the flank , generating a vortex that then trails behind the airplane .
