H,
More than happy for you to give input, but, if the sole driver is money, then ground rotary now, save yourself a bundle. But I will expect that same approach to every aspect of public spending. I am struggling to see why police aviation should be e whipping boy. I will take your answers as tongue in cheek, as m sssuming that's how it was meant.
To reiterate, ground them now, if it's about money. And not the service.
