On the BBC web site there is a useful timeline for the Hutton Inquiry here: Timeline: Hutton report.
One of the interesting aspects is that there are links to a number of contemporary videos.
Some of these give useful detail.
For example, in the video for 17th July 2003 (some of whose content seems to date to the 18th July) there is an aerial view showing the location of the Police vehicles relative to Harrowdown Hill wood. That view suggests that the body was located close to the north side of the wood.
