The mighty Avon 200 series Hunter engine was fired up with the essential participation of Avpin - possibly the most volatile liquid to transport by any means. How it arrived at Masirah (and elsewhere) I cannot recall but subsequent wanderings around Europe (2 Sqn - Hunter FR 10) led to several turn rounds at NATO bases where the host nation would only store Avpin in the most remote locations.
At Istres circa 1957, it was flown out in 44 gal drums in a Valletta from Benson. Then stored in the 'Avpin Hut', an isolated wooden hut in the bundu about 50 yards from the hangar.
