Now for our younger viewers - Environmental Terrorism

Continuing the theme of aeroplanes as weapons, I took this footage in west London on my lunch break.

The tall structures (dead flowers in an allotment), the blue sky, the plane, the fraying leaves and the sound of aircraft engines all reminded me of 9/11. But to me the planes looked weedy (weak joke, sorry), puny, pathetic, incapable of causing destruction.

I was going to try and edit the film, cut my flapping coat and shoes, but I changed my mind - there is something about the fleeing shoes that make me think of guilt, I can't explain why.
