Caught the tail-end of the Weather Show the other day and there was a piece
on "vapour trails". In it, they said that contrails were caused by jet
aircraft and, specifically, jet engines. Do these ignoramuses think the
Spitfire was jet-powered?

It was also said that persistent trails were a sign of rain and that a lack
of them meant the weather would be dry. From that I would gather that as
persistent trails don't occur in unstable cold air, neither do showers.

I hadn't thought the weather presenters could dumb-down the subject any more
but they've managed it.
