How does studying aurorae in Alaska translate to "chemtrails"
everywhere else?

I have seen con trails and chem trails in the sky at the same time in
Edinburgh and know the difference. The first disappears quickly. The
second expands and lasts and the particle fallout causes me chest
problems.

How is the astroturf?

you need better briefing!

The contributors to this group are very intelligent people and need
evidence not dogma!

Sorry for the rant.

Quite astonishing how far this thread has drifted! Perhaps if I had
given it the title "Vapour trails in South Bucks" some people not from
the UK might not have understood.
Nevertheless I am glad I have provided a platform for this obtuse
thread-spread.
Yesterday, in the glorious blue sky and warm sunshine we enjoyed in
South Bucks, our bit of the sky was full of vapour trails. Other
technical matters did not bother us - the questions were simple -
where did the plane come from and where is it going?
