He worked there for Austrian/Maltese oil company called VAOS (used to be Voest Alpine Oil Service but during '90s changed name to Value Added Oil Service) and was stationed at Mars El Brega, Ras Lanuf and Nafoora in period from 1987 thru Feb26th, 2011 when evacuated by RAF C-130 landing at Nafoora Airstrip. Airstrip was under construction for repairs so noone expected a Hercules landing there. First one that came was a RAF bird taking 50 workers (wintershall, Bonatti, VAOS, MAN) to Malta and the second Herc boarded remaining group of Europeans. Second Herc (the one my father was in was fired upon by local population (rebels). They also tried to puncture the tires but were beaten off by RAF/SAS servicemen on board of the aircraft. Hercs egressed 20m AGL over terrain and 10m ASL over Mediterranean. Too bad noone ('xcept reporters) wasn't allowed taking photos on board...
He was a VAOS - Nafoora camp supervisor and now had to report all VAOS equipment losses to rebels and locals but also to ex-military personnel (who joined rebels) and rushed in with guns and RPGs and confiscated all they found worthy and broke all they couldn't carry. He was shocked to see familiar Libyan faces from local villages he cooperated with turning hostile over night plundering what they lived off.
Last camp he supervised was VAOS Nafoora located at 29°15'39.68"E / 21°32'56.92"E (if you look at Google maps it's the one with grass field in between containers). I'll post some of his photos from Libya here although not related to topic of this thread for you to see if you wish!
