How did you know an air raid had finished?

Answer 1

An air raid typically ends when the all-clear signal is given, often signaled by a specific siren or announcement. People would also look for signs of silence, such as the cessation of sirens and the absence of aircraft overhead. Additionally, local authorities might provide updates via radio or loudspeakers to confirm the end of the threat. Observing the return of normal activities and the reassurance of emergency services also indicated that it was safe to emerge.
