Limited space here does not allow me to get into the tremendous amount of German technology stolen from the Fatherland in 1945. The Allies were so concerned about specific weapon sysytems and scientists that they made lists to target them including "Operation Paperclip" and "Operation Lusty". Others simply stumbled onto unknow secret facilities like those at Oberammergau, Ohrdruf, and Lofer, Austria and found: supersonic aircraft, revolver cannon, variable sweep aircraft, electrostatic cannons, EM weapons, nerve gases and worse, German disc craft, jet and rocket aircraft, escape capsules, ejection seats, spacecraft designs and spacesuits, cluster rockets, the upper component to an ICBM, super subs with stealth coatings, the first true stealth fighter, thermobaric weapons, AIP systems for U-boats, FAE bombs, advanced small arms, rocket weapons galore, every type of missile imaginable, super tanks, disc aircraft, unmanned aircraft, radiologicals, and two new atomic programs as well as knowledge of hydrogen weapons and uses for nuclear energy for power, nuclear subs, nuclear aircraft, etc... and more. There was so much classified data that special Intel services known as P.O. Boxes were set up to deal with these technologies and components of advanced systems that were unknown. The US got the lion's hare and moved them to Wright Field then New Mexico (where the UFO phenomenon started over military installations), then Edwards, and finally up to Area 51 and facilities buried in Utah. The disc craft were denied for 50 years and then admitted by the USAF. The Foo Fighters were known, but hidden from the public under the false PHOO BOMB designation to foil FOIA requests. EM weapons, rail guns, and stealth was kept secret. Nerve gases were manufactured and stored. German disc craft are classified until 2020 and the function of Jonastal S.III is classified until 2045! What in the world would cause the US to use 75-100 year classifications with these weapons and facilities? Because much of the tech is beyond Newtonian physics and the origin is being kept secret. Most of what the US claims as new tech from the 1970s-present is actually German tech now suitable for operation using more advanced materials and systems. The US Govt. has put out so much deliberate disinformation to protect its false historical "firsts" postwar. When the German achievements become known the history book will have to be changed in aviation and possibly spaceflight. The German atomic bomb projects (plural), radiologicals, and other exotic bombs are also kept under wraps. It took many decades to reverse engineer German disc propulsion systems and to make them viable for today, but moved into the black triangle craft. Disc craft are unstable and unreliable and no internal space b/c the powerplant takes up everything. The materials the Germans used are also classified like Luftschwamm and Viktalen armor. The Roswell aircraft may have used Luftschwamm as the mystery material that wouldn't burn and could reconfigure itself. The grooves on the bottom of the craft were also German anti-radar grooves found on the 3rd version of the Horten X design and the balloon? Possibly a FUGO type from Japan to carry ot over Soviet territory. It was a man-made machine and never alien. Food for thought, eh?
