Have you ever experienced St. Elmos fire on a large aircraft?
Yes I have. Its amazing. I have seen two types. One where there was purple plasma surrounding the entire nose of the aircraft and jetting off of the windshield wipers. It looked like purple fire just covering us. The other was like little lightning bolts crawling over the windshield. The best analogy I can draw is the end of Return of the Jedi, where the emperor was shooting lighting at Luke. It looked just like that.
