Titanic's Tragic Twin: The Britannic Disaster

SYNOPSIS

The Titanic's twin sister, the Britannic, was bigger and better built, but she sank to the bottom three times faster. Why she sunk has remained a mystery until now.
On the 100th anniversary of the sinking of the Britannic, Kate Humble and Andy Torbet piece together exactly how she suffered the very same fate as her sister ship the Titanic, despite being re-engineered to be even stronger than the tragic liner.
