Residents all throughout the Midwestern United States reported seeing a brilliant, blue-white flash lighting the sky for several seconds on a clear night in October 1997. Unlike most lightning, this one happened amid calm weather and lacked thunder. Many of the hundreds of witnesses said the light was abnormally brilliant and clearly blue in colour; some claimed it was sufficient to create shadows. Meteorologists, astronomers, and government agencies have conducted a lot of research but never a good answer for the phenomena has ever been discovered. Though none could completely explain the features of the occurrence, theories varied from a meteor explosion to covert military testing. The absence of any tangible proof or matching radar data has simply heightened the mystery. Still one of the most puzzling and often observed inexplicable meteorological phenomenon in recent history, the Azure Flash of 1997 tests our knowledge of natural events and fuels ongoing discussion among both scientists and the general people.
