Timewatch joins the crew and passengers on board Britain's favourite ship as the QE2 leaves Southampton for the last time and glides gracefully into retirement. In 1967 a newly-built ship launched a remarkable love story. The QE2 captured the heart of the nation and became a Great British icon. In her 40 years in service, the world's most famous cruise liner has sailed more than five and a half million miles, carried more than two and a half million passengers and crossed the Atlantic a staggering 800 times. She has also survived terrorist threats and war.
