Very interesting. I'm still to take in all that you've written, but just to clarify for the mean time, the BBC and the general view (I'll be brief, as am having to run here) is that these trails (numerous on most days) are harmless vapour from aircraft flying at a certain cruise altitude (I've done a few calculations myself and can see this explanation to be nonesense). So, no, no-one, including environmental groups (all government controlled)who will ignore, slate and censor you at the slightest hint of mention, admits to 'chemtrails' as such. If anything your lot over there are alot more open and enlightened than people in this country, trust me!
