Instead, they will arrive back to RAF Brize Norton, where they will be driven through the back gate and then down side roads, neatly avoiding the nearby town of Carterton, as they make their way to the John Radcliffe Hospital in Oxford.
If you drive through the back gate it takes you directly into Carterton.
And if they mean side roads as in the A40, then I guess they must have big roads elsewhere in the country.
