A large number of Civil Defence and fire brigade personnel attend to the destruction caused by a V1 incident in 1944 on Aldersgate Street in London. Five people were killed and dozens injured. The photo shows a lot of 'white hats' both senior and junior supervisory roles. A Controller (white helmet and two narrow bars over a broad bar on upper sleeve) and a District Warden (in beret with three narrow bars to upper sleeve) talk to an MO (Medical Officer) and many helmets show LR (Light Rescue) in the background.
