Settlements: A40 explosion, October 1957. Scethrog
Due to fog the drivers of a lorry loaded with three and a half tons of TNT destined for an opencast site in Glynneath stopped to clear their windscreen only to find a rear tyre on fire. Realising the danger they ran up the road to warn motorists when there was a massive explosion. No one was hurt but houses in the vicinity especially the Scethrog Post office were badly damaged.
