Extremely hard to document (and scanty at best), is the Case of a ''Mystery Explosion'' which was recorded near Beijing, China in the year 1626 AD. The massive explosion was said to have been felt for hundreds of miles (by some). Recorded by Ming Dynastic Historians of The Era – many felt that it was ''divine retribution'' by The Gods for the then Emperor's lack of proper governing. Much money was being spent on the renovation of The Forbidden City of Xian, rather than help feed His people (then starving from a long famine). Some accounts say that a ''great ball of light opened'' over The City, followed by a ''crack of sound''. This was followed by a ''massive mushroom shaped cloud''. The sky grew ''black as night'' with ''pieces of bodies cascading down from the sky''. Those bodies found in relative tact were all said to have had their clothes ''burned off''. It was further noted that a strange'' silk-like substance'' began to ''rain down from the sky for hours after''. It is speculated that as many as 20,000 people perished (including The Emperor's only Son, The Prince). Soon thereafter, The Dynasty would fall.
Just what did The City experience? At first glance, One may assume it was a Bolide (Meteor) strike, noted for their instantaneous ''air bursts'' (as the often ''Official'' explanation for the similar Tunguska Incident in Russia in 1908). However, the descriptions of the victims as well as the strange ''silk'' substance falling from the sky, sound suspiciously like radioactive fallout from an explosion. This can't be (at least for MANY more Centuries). One explanation put forth, was The City's store of gunpowder. Becoming unstable due to improper storage, a spark could well have caused a massive explosion – but again, nothing of the magnitude of what was experienced. How could a nuclear explosion happen in 17th Century China? Some say that it may have very well been a case of an early ''Roswell Type'' incident, in which an Alien Craft crashed into or exploded above the City. Such an explosion – especially if it involved any form of what we would see today as ''exotic propulsion or weapons'', could have caused this ''accident''. But even today, The Mystery Explosion at Wanggongchang has NEVER been explained.
