That hasn't stopped you.
I did not say it was likely. Rather the opposite. But if you start saying things are impossible or don’t exist without googling first you just set your self up for embarrassment.
Oh I don't feel embarrassed at all. Now, if I took a weapons system that is being experimented with now, and said it might have been tested 20 years ago, by an entirely different country, in the busiest air corridor in the world, and really thought that was a possibility, then I'd be embarrassed.
Apparently you don’t know the difference between the words ‘possible’ and ‘likely’. If you think I made an ‘absolute statement’ then I suggest you go spend some time with a dictionary.
