I was in country training pilots for the local air force who had bought a plane from my employer. Once a month we would fly the military payroll around the country. Of course this was cash, so flying it was by far the safest way.
Before we went North, the pilots would call up there for weather.
it would always be clear, even though when we arrived the sand was blowing so hard we could barley see the ground, and the runway was the same color brown with just some markers to outline it. The deal was, if we didn't get in, they didn't get paid until we did, so we always were told it was good VFR just to get us to try!
