It was the Von Richthofen flying circus. They were coming in low. They filled the sky from end to end. Someone on the ground was shouting- maybe he was giving orders- but I couldn't hear the words because of the drone of all those machines. It was like the moment in a dream when the supernatural stalker has your back against the wall and there's no possible way of wriggling free. The time I spent seeing those skeletal forms imprinted on the china sky- the time between the first warning and the start of the strafing- was absolutely the most terrifying of my life.
