Homes, businesses and a school were evacuated and roads closed after a World War Two bomb was found in a quarry in Dorset.
The device was discovered by a worker at Henbury Quarry in Corfe Mullen, Dorset, on Tuesday morning.
A 1,000m (0.62 mile) exclusion zone was set up around the sand and gravel quarry in Old Market Road.
An RAF bomb disposal team destroyed the device in a controlled explosion shortly after 10:15 GMT.
A rest centre was set up for residents at the Memorial Hall, Sturminster Marshall.
Staff and pupils from Castle Court School were taken to another site ahead of the explosion.
Brimstone Site Investigation spoke 5131 (BD) Squadron to ascertain their disposal technique, it transpired that the RAF opted for a low order technique in dealing with this massive WWII experimental Barnes Wallis creation, fortunately the Unexploded Bomb (UXB) was concrete filled this time.
