Historic US ocean liner moves out of Philadelphia after nearly 30 years

The SS United States, once the largest passenger ship built entirely in the US, has been towed from Philadelphia after nearly 30 years.

Launched in 1951, the ship was a symbol of luxury and innovation, carrying nearly a million passengers before its retirement in 1969.

Now on its way to Alabama, it will be intentionally sunk to form the world's largest artificial reef.

This transformation aims to support marine life and attract divers to the site.
