Melchett,
The sainted lady's birthday bash isn't meant to be a demo of operational effectiveness, y'know.
Otherwise the RAF would just pop a brace of Paveways into Regents Park Mosque for effect and crate up a few Chinooks for dispatch by Russian charter flights to some far away country where they're not wanted. Meanwhile the RN would use HMS Ocean to run a water taxi service up the Thames for a few hundred illegal immigrants from Calais.
