For the first time I was flying by jet propulsion. No engine vibrations. No torque and no lashing sound of the propeller. Accompanied by a whistling sound, my jet shot through the air. Later when asked what it felt like, I said, "It felt as though angels were pushing".
What is the knocking? What is the knocking at the door in the night? It is somebody who wants to do us harm. No, no, it is the three strange angels. Admit them, admit them.
