I must say I do enjoy reading all the inter service willy waving. But here is a warning. Get in as much as you can right now, as due to soon to happen defence cuts, there will soon be no point in continuing.
Noo Labour are going to scrap everyone's kit, and replace it all with just ONE hovercraft (land,sea, air use). After that, each of the services will get to use it for ten days at a time in rotation.
Although, knowing UK procurement, it will no doubt be delayed for several years, while the powers that be argue over whether it needs air brakes, an anchor or disc brakes!
Going back to King Airs briefly. I would also like to know as much about them as many other PPRUNERS, but then I am not in a need to know position, so will just have to wait.
