Hello all,
Thanks to Terri for the invitation to contribute... I also thought the time of day of Terri's post (the one just before this one) was quite interesting!
I think these planes are fairly similar in physical size and fairly similar in height in the sky. One has a trail - the unmarked one - and the other has none.
Admittedly, the trail from the unmarked plane is not a long, durable chemtrail - but I think this photo is possibly of some interest.
Come on - I am sure you can get better shots than this!
Just another note, local BBC Derby responded when I asked to make a film about "Aircraft Trails" - that was over 2 years ago now...
A shame they couldn't get someone better than muggins here to do it... Not had any feedback...
Thanks for reading.
