craggenmore doesn't tell you the whole story:
Currently there are 3 a/c nightstopping in FCO. These a/c are crewed from mxp, therefore mxp is overcrewed. If they were to get "external" crew, mxp would remain overcrewed, which is of course not ideal. So the company hopes that there will be enough volunteers to go from mxp to fco, and I can think of a few, so that both fco is crewed and mxp is at the right crewing level again.
If there isn't enough interest from mxp based pilots to transfer, anybody else in the company can bid for fco, based on doj.
Base opening on 2nd of nov 2009, which will also see the amount of a/c go up to 4 initially.
