Cockpit Footage of St. Elmo's Fire

View from the cockpit showing the coronal discharge known as St. Elmo’s fire (actually plasma not fire). The electric field around the object causes ionization of the air molecules, producing a faint glow easily visible in low-light conditions. Approximately 100 - 3000 kV per meter is required to induce the effect; though this number is greatly dependent on the geometry of the object in question.
