I was rather puzzled by the article about Paul Triballi and the vapour trails over Sussex (The Argus, March 4).

I have taken many pictures over the years in which airliners coming from Manchester, Liverpool, Newcastle and the like are at a higher altitude and therefore leave smaller trails when they pass over the South Coast. The larger trails from east to west are considerably lower. This was shown in the photograph.

The formation to the right of this picture was mixed with some thin evening clouds, as the picture was taken in the evening sky with the sun setting. I would certainly like to see more of Paul's pictures.
