The book is organized as a day-by-day chronicle. It shows in words and pictures what happened when hundreds of commercial airliners were unexpectedly grounded, stranding tens of thousands of people far from their homes. It shows the memorial services that were held everywhere, particularly on Parliament Hill in Ottawa, where 100,000 people gathered. It shows the steps that Canadians took, both as individuals (for example, by assisting in the work at Ground Zero), and as a nation (by mobilizing our armed forces).
