PLANE FLYING INTO A “TIME VORTEX”

“The air flow from the wing of this plane is made using colored smoke rising from the ground. The swirl at the wingtip traces the aircraft’s wake vortex, which exerts a powerful influence on the flow field behind the plane.

“NASA researchers are studying wake vortex to create an automated system that could predict changing wake vortex conditions at airports. Pilots already know, for example, that they have to worry less about wake vortex in rough weather because windy conditions cause them to dissipate more rapidly.”
