National Iron and Steel Heritage Museum.

Guppy: Two-Person Sub

The Guppy was built as a two-person sub with Lukens Steel from the Coatesville steel mill -- now part of the National Iron and Steel Heritage Museum -- and it's only right that it has returned here. The museum also has cool outdoor displays including a "sonarsphere" and one of the familiar steel "trees" that once wrapped around the base of the World Trade Center Twin Towers -- which were made in the Coatesville mill as well.
