Forces sweetheart Katherine Jenkins is joined by Michael Aspel to celebrate the heroes of the Home Front in a special week of programmes to commemorate the week 70 years ago that Britain went to war with Nazi Germany. On January 20, 1943, a German plane dropped a bomb on a south London school in broad daylight, killing 38 children and six teachers. The programme talks to some of the survivors and pays tribute to the ordinary men and women who helped save their lives. Also, antiques expert Tim Wonnacott searches for the everyday wartime objects that have become collectables.
