Ghosts in the sky

There were some really bizarre clouds this morning over east London. It either looked like:

1. Someone had forgotten to put any up there, and had just grabbed the white paint brush and had a few wild strokes

2. The clouds were getting jealous of the vapour trails and figured they'd 'have a go'

3. Or there was some sort of catastrophe at the home of the Ghostbusters and they'd accidentally released the slowest-moving, least-threatening white ghosts ever into the sky.

Take your pick!
