Your quite right of course. The small amount of available work, and the high costs associated with getting set up in the first place now make it a definate non-starter. Our aircraft used to do the winter in Greece just to keep them busy all year round. They've since been exported out there permenantly, so I don't know what became of them. For each aircraft we had 2 support wagons, each with a crew of 3, plus pilot, plus ground 'mapper' who worked a day or so ahead of the aircraft, so a team of 8 per aircraft. Crikey, doing the sums on that would make it far too expensive at todays rates to even consider.
