Crash in Westgate Street

About 50 years ago I was walking down Westgate Street (It was one way in the other direction then) and heard a tearing sound, looking up a lorry had hit a sun-blind and people were running to get away.
This was my snap, now bear in mind there was no auto exposure, focus or motor wind and I always left winding on to just before I clicked the shutter to save the shutter springs.
I think I was very lucky to catch the moment.
