My first hand accounts of life at RAF Helensburgh reflect how dangerous and sometimes how amusing it was testing airborne anti submarine warfare. i.e. Sqd Ldr Tennis Tanner remembered trials of anti submarine bombs fitted with experimental devices to prevent premature explosions. One sunk without going off. A pinnace arrived from Helensburgh to collect floating fish for supper. 'The bomb went off and hit the pinnace like a sledge hammer. Fortunately, the water was deep and the pinnace stayed afloat. The crew made it back to base but did not fancy fish for supper.'
