Well, I'm not a chemist and I agree that it seems highly unlikely that the government could hide something like that, but I have always wondered if
its only vapor, why does it seem to linger so long, and why does it sometimes give off a gold to brown color? Again, I am not really a supporter of
these theories, but I wouldn't mind maybe a pilot or a chemist's point of view on the nature of vapor trails.
