Nivsy, the simple economic reality mayby that these published guidelines will guide Monarch to stop operating into the rock...it makes no sense for a commercial operation to endanger its bottom line on the basis of a levy dictated to them and deemed "appropriate" by those who have a vested interest in saying so. Government/MOD etc...have a far from umblemished record of cost efficiency, perhaps it is "appropriate" for Monarch to take its business elsewhere?
