Airborne over Wadi Hadramaut in eastern Yemen. Because of the dramatic relief (up to 300m) between wadi & jebel we used helicopters on the seismic acquisition crew and all equipment was flown out to the line. This is the view as the aircraft tops the jebel. We had one ex-Vietnam vet pilot who used to delight in giving visiting newcomers a gentle take off from the jebel, fly slowly across the edge of the cliff & then immediately drop vertically down 500ft into the wadi. An exhilarating experience to say the least. Unfortunately he was later in an accident when the engines cut-out at about 100ft when he was long-lining & the helicopter fell to the ground. Amazingly he kept the aircraft upright & survived with minor cuts & bruises but shortly after he decided enough was enough & took retirement.

Waiting to board a Pilatus in the Sahara desert south of Hassi Massouad. We were en route to a seismic crew shooting a survey in the Lasmo-operated El Ouar drilling permit, Algeria. It was pretty cramped for the first stage of the journey from Hassi with a full complement of passengers in the small aircraft but after dropping off most of them at this wellsite the two of us flying on to El Ouar could spread out. It was said that El Ouar meant "the worst" in Arabic referring to the the sand dunes being the most impassable. They had a relief of up to 1000ft and were so dense that it was impossible to drive/walk around them. This meant some serious climbing was needed to progress through the area. While the dunes gradually increase in size & density from the north to the south the dune belt stops very abruptly along a southwest-northeast line. I have flown over the area since on the way to West Africa & from 30,000ft this change from sand to rocky desert is very clear & hence it is easy to locate yourself.
