Just had the excitement of seeing a con trail overhead. Con stands for condensation, it’s when a jet airplane flies high up and the hot and humid exhaust gases from its engine condense out as ice crystals in the very low temperature and low vapour pressure air. Its like when you breathe out in the winter and your breath turns into ice if its cold enough.

For some reason there is a conspiracy theory that the vapour is made of chemicals and that governments are spreading them from the planes.

Ask yourself, why would they do that? There were experiments in the mid twentieth century to try and ‘seed’ clouds to make them rain. But it didn’t really take off!

It is strange how these weird ideas get into the world. I prefer thinking things through. If it doesn’t make sense can it be true?

Anyway I don’t think one con trail makes for the end of the lockdown here, like the old saying ‘one swallow doesn’t make a summer’. And really, I for one would like there to be a lot less flights, or more ecologically sustainable ones when things do resolve themselves.

In the meantime please stay safe.

Good morning.
