How does Ian Fleming use imagery in Moonraker?

Imagery:

A pigeon "came to rest on the window-sill with the same clatter of wings. It walked up and down, nodding and cooing, and then planed off towards the trees in the park. The traffic murmured sleepily in the distance. How nearly it had come, thought Bond, to being stilled. How nearly there might be nothing now but the distant clang of the ambulance bells beneath a lurid black and orange sky, the stench of burning, the screams of people still trapped in the building. The softly beating heart of London silenced for a generation. And a whole generation of her people dead in the streets amongst the ruins of a civilization that might not rise again for centuries."

Bond "was greeted by a scene of such splendour that for several minutes he stood speechless, his eyes dazzled by the terrible beauty of the greatest weapon on earth."
