Kelvin-Helmholtz clouds over Sydenham?

Re the oak processional caterpillar, don't be so sure they are safe, Tim. I had a bad allergic reaction while coming into contact at site they infested years beforehand. Just the dusty residue left in the nearby structure was all it took for my face and eyes to burn and swell...... No lasting damage, but scary indeed.

It was a Blue Öyster Cult reference, and they were actually pine processionary moth caterpillars.

the line of clear sky is either where one plane has flown through the cloud creating the clear path, or more likely it's where two planes have followed a similar path, a short distance apart, and left a gap between their 'chemtrails'.

Condensation trails, not ‘chemtrails’, unless you are a conspiracy theorist. https://en.m.wikipedia.org/wiki/Chemtra ... acy_theory

When I say it - it was probably several miles wide at 6:30pm. Not even a squadron of Russian 'Bears' flying tip to tip could do that!
