So the sum total of the gains from joining NPAS = zero..
This is not strictly true, This is the price of going it alone, partially. Had SYP joined NPAS they would be paying substantially less, albeit at the loss of their aircraft and relying totally on other units.
I am glad I don't work at SYP, if they are covering 'Peak deployment' then it's no social life, no home life..........sounds like fun.
