This week we finally unpack Charles Dellschau's forgotten aeronautical notebooks and learn how long-term nuclear waste warning messages are created. A listener email digs up the story of how the Brynlow shovel was dug up out of Alderley Edge but not identified as a Bronze Age tool until many decades later.
