While embedded with troops in Afghanistan in the late 2000s, war photographer and writer Michael Yon captured numerous photos of the sparkling halo that can appear when a helicopter’s rotors hit sand and dust. Upon finding that the particular phenomenon didn’t have a name, Yon gave it one that honors two fallen soldiers: the Kopp-Etchells Effect.

The name “Kopp-Etchells Effect” is now widely used when referring to dazzling helicopter halos, which commonly appear when powerful military helicopters take off or land in sandy environments.
