It's called the Kopp-Etchells effect. It looks like a computer-generated effect but it's just an act of nature:
When helicopters pass through dust storms, contact of the particles with the rotating blades produces either sparks or static electricity. The phenomenon has been observed during combat operations in Afghanistan; Michael Yon has documented the effect, and has named it after two U.K. soldiers who died there.Violently beautiful, huh?
