Slb is correct. Marsa El Brega in the SE corner of the Gulf of Sirte.
I was in a group that was visiting the Sirte Oil Company in the late 80s. Confusingly, Sirte Oil is based here and not in the town of Sirte.
We were told that the north end of the runway had recently been extended out onto the “sabkha” by building a 20’ high embankment. The extension was to accommodate Ghaddafi’s 707.
We stayed in Ghadaffi’s “guest house” which was surprisingly austere.
The best thing about my one week trip was getting on the Swissair DC-9 to take us out of Libya. The cabin crew refused to get out of the aircraft during the turnaround!
Slb has control.
