In November 2002, the Royal Navy's Trafalgar-class submarine, HMS Trafalgar, ran aground close to Skye, causing £5 million worth of damage to her hull and injuring three sailors. It was travelling 50 metres (160 ft) below the surface at more than 14 knots (26 km/h) when Lieutenant-Commander Tim Green, a student in the Submarine Command Course, ordered a course change that took her onto the rocks at Fladda-chùain, a small but well-charted islet.
