The need to be Fulfilled.
With the capture of much Axis powers hardware this former German design was now updated met a new era of work in the rushed Vietnam war scenario. The aircraft proved to be an invaluable tool against both Soviet Russian and Chinese aircraft and other roles were found for it in search and rescue by both the U.S. Marine corps and USAAF/Navy.
West-Germany, Thailand and several other countries bought into the type from the 1960's to the mid 1980's, but since then this role has been replaced by unmanned drones which are cheaper and safer to use? In fact this has become the fate of the many Nazi-German aircraft, clever and advanced in 1944/45 but they have now seen their days over the last fifty years.
From the ancient Chinese to Halloween.
Fire works were developed by the Chinese initially for the pleasure, very much as they are used today to mark a celebration or event globally.
But for a time the humble firework became a weapon from ancient China-Mongolia to the 17th Century French. The British Royal navy, and the U.S developed it as a distress flare.
The rocket came to its fore as a serious artillery piece during World-War-II (1939-45) where all allied and Axis sides had their own versions. Soviet Russia really when for the rocket from its Katyshka platforms to the BM-21 which remains in service across the world.
The humble firework today still finds other uses such as in demonstrations with the police and in pipe-bombs by most terrorists and other criminal groupings.
