The last of Deano P's pics very likely Dhala, showing the 'bend' in the strip which required a"left hand down a bit" part way through the take-off run. We, APCSS/84 'pigs', didn't operate there but the Pembrokes did.
In one of the previous posts, a contributor asked whether the sandy conditions affected engine operation. It did! 78 Squadron set up with Single Pins initially and they experienced a number of engine failures. Investigations took a while before it was discovered that the sand ingested into the engines was being turned into glass and deposited on the plugs.
