For urban dwellers who have quelled their fears of tall buildings, small spaces, and cement covered earth, when disaster falls, the mystery is why this time? Why these people? Hatred has a river of causes that rush together beyond anyone's control. The minute by minute unfolding of events felt like holding human destiny in one's own hand. To watch one plane and then a second plane approach and approach, when each second they could have turned away, was to behold the mystery of evil.
I drew the outline of the approaching planes over and over as an overlapping memory that could have been changed at any chosen moment.
