Illustration of St. Elmo's fire on a ship at sea Electrostatic discharge flashes across the windscreen of a KC-10 cockpit.. St. Elmo's fire (also called witchfire or witch's fire [1]) is a weather phenomenon in which luminous plasma is created by a corona discharge from a rod-like object such as a mast, spire, chimney, or animal horn [2] in an atmospheric electric field.
The pilots who captured St. Elmo’s fire outside their cockpit window this week likely weren’t in any danger. St. Elmo’s fire on its own is not dangerous. And planes are equipped with devices ...
