electromagnetic fields ionize the different gases in the atmosphere creating bright lights and different colors. superconductors emit electromagnetic fields. there have been materials developed, likely a combination of different things brought together in a specific way, like creating an alloy or some type of ceramic material. and this material is a stable superconductor that doesn't need extreme temperatures to remain in a superconductive state. they use this material as a coating or shell for various types of aircraft. high speed levitation trains use similar technology, they use liquid helium refrigerators to maintain the cold temperatures required to achieve superconductivity. its called the meissner effect when super cold objects can be come magnetic or produce magnetic fields. its also described as flux pinning or quantum locking. and its what makes things like "antigravity" possible.    aihzzmfs   566ep0hg
