A BSA M20 motorbike, provides a poignant reminder of both the futility of war and the ability of nature to heal. Now completely encrusted in coral, it was part of a cargo on the SS Thistlegorm, destined for the 8th Army in the Western desert. The bike (and lots of other fascinating cargo) has been on the sea bed at Sha'ab Ali, near Ras Mohammed, Egypt since 1941.
