Now jumping back to the Calanscio Sand Sea in eastern Libya in 1991 for a photo of a hard landing.
For today's photo I'm going back to 1990 and the sand dunes I worked in western Libya and where one of our drivers was learning to fly.
Today's photo is of our mechanics' desert workshop. Here these five or six guys would keep out fleet of 30 or more Land Rovers and trucks running - plus the generators!
Here's a broader view of yesterday's photo. From here, the only way is up! With the surveyor standing by the blue Land Rover, you can see the Wild T3 Theodolite on the tripod and the Wild DI4L or DI5 distomat mounted on top of the theodolite.
Today's photo is of a Caterpillar D8 (or D9, I'm not a Cat expert) cutting through the top of an escarpment to create a new pass.
What this photo actually shows is a stretch of the Libyan-Algerian border about 90 miles (140 km) south of Ghadames. Libya is on the left, Algeria is to the right, as if you couldn't tell for yourself!
