The images on television have been heartbreaking.
People on fire leaping to their deaths from a hundred stories up. People in panic and fear racing from the scene in clouds of dust and smoke.
We knew that there must be thousands of human beings buried alive, but soon dead under a mountain of debris. We can only imagine the terror among the passengers of the hijacked planes as they contemplated the crash, the fire, the end. Those scenes horrified and sickened me.
