Thanks for the update Jamex. I see Amberely is also approved - just a few ks from where I am sitting.
As far as I can glean, only about 3 of the sites are active on an STS mission - needs loads of kit for defuelling etc etc. The 3 sites are chosen for the abort modes at launch & I gather are abandoned as soon as it reaches orbit, from where it can always abort back to the USA.
But lets get back to the handbag swinging on this thread...
