That there have been chem-trail experiments (as we know various substances have been released on unsuspecting populations over the years), or that, at the very least, such experiments have been proposed is surely in no doubt. Take care with your generalised "debunking", There is good evidence for the secret testing of many militarised technologies (such as seismic weapons, weather weapons, biological weapons using animal and/or insect vectors etc.).
Here's a little recent tit-bit that should be of interest re: #OperationPaperclip T; "Frank Döbert and Rainer Karlsch
Immediately after the end of World War II, the victorious powers began to interrogate the functional elites of the National Socialist state. When the question came to the German V-weapons programs, jet fighters and underground armament factories, the name of Hans Kammler was mentioned again and again. In the final phase of the war, the SS Obergruppenfuehrer and head of the Office of Unit C of the Economic Administration Main Office of the SS had been given far-reaching competences for the production and use of the latest weapons. The Allies were aware of Kammler, even though they knew far from everything about his “underground shadow realm,” his role in the Holocaust and the mass use of concentration camp inmates in construction projects. They searched intensively for him, but, according to the standard narrative until only a few years ago, came too late. Kammler had allegedly evaded his culpability and committed suicide in Bohemia on 9 May 1945. Doubts about this account, however, were never completely silenced, especially since his body was never located and all personal documents remained missing. Gerald Fleming, a leading Holocaust researcher, wanted certainty but could not find sufficient evidence to prove that the suicide narrative was not true. Fleming urged us not to let the story rest but to continue the research. 
In the article „Ein inszenierter Selbstmord. Überlebte Hitlers „letzter Hoffnungsträger“, SS Obergruppenführer Hans Kammler den Krieg? [A staged suicide. Did Hitler’s “Last Hopeful,” SS Obergruppenfuehrer Hans Kammler, Survive the War?], published in the Zeitschrift für Geschichtswissenschaft in 2014, for the first time declassified documents and statements were presented which suggest that Hans Kammler was captured by the Counterintelligence Corps, an American military intelligence service.".."The most important evidence for this thesis was a report by special investigator Oscar Packe dated August 1949. Packe, who worked for the department of the U.S. military government in Hesse responsible for denazification, concluded his report as follows: “The suicide of the subject, suspected and allegedly confirmed by the witnesses, is refuted by the CIC’s precise information about his capture and escape in May 1945. Evidence that the subject is now in Soviet custody and is to work in the Soviet occupation zone of Germany could not be provided here.”
Packe had been informed by the CIC of Kammler’s capture and subsequent escape. Was it possible for a high-ranking SS general and his staff to escape from American captivity? Was he really arrested with his staff at the Messerschmidt works in Oberammergau, as the Packe report states, “by American troops on 9 May”? And was able to escape from there with senior SS leaders of his staff? Did the events in fact take place near the underground Messerschmitt plant “Bergkristall” in Gusen, near Linz? It is likely that Packe did not learn the true circumstances of Kammler’s arrest from the Counter Intelligence Corps. Recently Donald W. Richardson, a special agent of the CIC and the Office of Strategic Services (OSS), has emerged as a key. Shortly before his death, he told his sons that he had brought Hans Kammler to the United States. For reasons of national security, he had to remain silent about it. Despite these sources and Richardson’s statement, doubts about the chain of circumstantial evidence persisted.
Now, however, newly obtained documents prove unequivocally that Hans Kammler was indeed captured by U.S. services. The documents were discovered by two researchers independently of each other: Marek Michalski of Poland, affiliated with the museums of former concentration camps in Treblinka, Stutthof and Groß-Rosen, and the Linz-based television journalist Andreas Sulzer of Austria." https://www.wilsoncenter.org/publication/hans-kammler-hitlers-last-hope-american-hands
