Coming Up For Air by George Orwell:
A noise like the Day of Judgment, and then a noise like a ton of coal falling on to a sheet of tin. That was falling bricks. I seemed to kind of melt into the pavement. “It’s started,” I thought. “I knew it! Old Hitler didn’t wait. Just sent his bombers across without warning.”
And yet here’s a peculiar thing. Even in the echo of that awful, deafening crash, which seemed to freeze me up from top to toe, I had time to think that there’s something grand about the bursting of a big projectile. What does it sound like? It’s hard to say, because what you hear is mixed up with what you’re frightened of. Mainly it gives you a vision of bursting metal. You seem to see great sheets of iron bursting open. But the peculiar thing is the feeling it gives you of being suddenly shoved up against reality. It’s like being woken up by somebody shying a bucking of water over you. You’re suddenly dragged out of your dreams by a clang of bursting metal, and it’s terrible, and it’s real.
