Elaine is joined by Dr Pamela Buchan, Marine Social Scientist at Exeter University and Brigadier Mike Tanner, Naval Base Commander at Devonport Dockyard. Together they look at the historic role the Dockyard has played in Plymouth and its effect on the environment in and around Plymouth Sound. We also discover our guests' passion for water and why the Brigadier's physique prevented him from having a different career in the RAF...!
