take this the right way Dave Reid because it is meant in an entirely complementary manner but there are very few posts I have made where you haven't been able to add a polite correction or some useful interesting additional info.
indeed what drew me to the subject of yesterdays post was the sheer brilliance of the white contrails against the blue sky and the fact that they were billowing out behind like steam engine smoke , a lovely sight. Probably the very cold atmosphere and the fact they were at FL250 not FL350 meant I was just getting a much better view of whats the norm but another 10000 feet up
Anyone know where they were coming from or did I miss that
