Tigerfish, what makes you say that support from neighbouring bases is now a mere shadow compared to pre NPAS?
What evidence do you have to back this up?
Since I've been part of NPAS I've had quite a few jobs where we have requested another aircraft whilst airborne. This provides a seamless handover with ground units and control rooms and means no loss of service due to fuel. It's also very easy to do as we are all on the same radio channels. That didn't happen before NPAS.
Looking at the NPAS Twitter accounts I've seen Benson, Birmingham, Bournemouth, Halfpenny Green, Exeter and St Athan all going into Bristol for jobs. Did this happen before NPAS when you worked there?
I think your way off the mark with your comments and you appear just to be jumping on the NPAS bashing bandwagon.
