<<when we very well know that similar activity as many of you here exclude, has been officially admitted to have occurred in programs over several decades, both in the US and UK>>
You say that "we know". Who is "we" please? I was an air traffic controller in the UK from 1970 to 2002 and I know nothing about such things. Perhaps some controllers who were involved with these activities would care to comment please? You can't have aircraft spraying chemicals without ATC knowing about it - or, at least, be aware of aircraft carrying out strange activities.
More please......... like official references.
