The NPAS structure was wrong right from the start! Yes it is a NATIONAL Police Air Service, but the National bit should only have meant Policy and Central purchasing etc. Service Delivery should be on a Regional basis not a national basis. Regions know what is best for them, and should be able to act accordingly. After the West Yorkshire failure, It is understandable that no force wants the same problems, but a Regional responsibility would be well within the capabilities of most larger Forces.
This went wrong right from the start when NPAS was set up with only one main aim, - that of Saving Shed loads of money! Increasing efficiency and effectiveness was never the aim!
