teilo,
You say that you had no camera and in any case there's a flood of photos on the internet. I am fairly new to this forum and haven't seen any videos on the internet matching what you describe. What these trails consist of is another matter. What is needed is a video of this event. If anyone out there has or is able to get hold of something like this, I would be extremely grateful, if it were made available on this forum.
As for the question of why chemtrail spraying is taking place, I have tried to find out if the metals sprayed have anything to do with the HAARP research program. It seems far fetched and an author on this subject, Jerry Smith, has state that he too suspects a link but has no evidence to support it.
