Barry, Nottingham asked:
Sitting in our kitchen, looking at aeroplanes out of the window I noticed a different colour in front of the plane, as the plane moved along through some wispy cloud. As it crossed the sky there was a section in front of it that was darker. It almost looked as though the cloud was dispersing well in front of the plane as the plane went along. I wondered whether thereís any way that the plane itself could be causing the cloud in front of it to disperse quite a distance in front of it, almost like the cloud is expecting it to arrive!
(Barry also said that the Sun was to the left, and relatively low in the sky)
The picture shows a plane flying through the sky with the usual contrail, the exhaust fumes of the plane, and extending in front of the plane is a very long black, thin line on the picture.
Is that the actual picture from the listener, Barry?
Sort of related.
Yes it did come from Barry. daveshorts, Wed, 23rd Jan 2008
