I was at St. Mawgan heading down the hill and wondered why a Hunter kept doing circuits, it turned out to be several aircraft arriving. The next day, alongside a line of Hunters parked on the end of the old 26/08 runway, I saw 45 gallon drums being stirred and was told it was Napalm being made.
From the radar section it was possible to see aircraft running in to drop ordnance, they showed up clearly on the bays ASV21.
