9/11: HEROES OF THE 88th FLOOR
TLC, 9:00 p.m. ET
This TLC documentary was originally televised last year, on the 10th anniversary of the 9/11 attacks. It tells of what happened on the 88th floor of the North Tower of the World Trade center, and the efforts of people outside — and especially inside — the building to save as many lives as possible. Three days before another 9/11 anniversary, it’s a grim but good reminder.
