"Sometimes Buckley said "Roger," or sometimes he said "Takeoff," but when he was most frightened and giddy and waiting for peace he just said "Yes!" And my father would take the thin cotton top sheet and bunch it up in his hands while being careful to keep the two corners between his thumb and forefinger. Then he would snap it out so the pale blue . . . sheet would spread out like a parachute above him."
