On November 7, 2002, the DND were still doing their demolition blasting exercises at Bentinck Island. (not Oct 7 as stated in this draft version of the video) The students from Lester Pearson College who were out for a project week were able to catch the images of the impact of these blasts on the first day from the science centre window and on the second day from the top of the light tower. In the tower, they interviewed Mike Demarchi of LGL who is currently doing a $50,000 contract for the Department of National Defence to monitor the impact of these blasts and to compare them with other disturbances at Race Rocks.
