PBS Video of WTC Construction

I don't visit the "dungeon" often, so forgive me if this is a dupe.

Edited to add:

I think you'll find the answer to the "steel or concrete" debate in Part 2.

Construction of the towers could now proceed with great speed. Three basic elements were used: two- or three- story sections for the load-bearing wall, massive steel beams for the core columns and floor sections to span the sixty feet between core and wall. Through the complex orchestration of these structural elements, three floors could be constructed in ten days.

1. A lot of the first part deals with the concrete construction.

But that's the underground part, seven stories deep.

Anyone who believes the official story should wonder why there wasn't a huge investigation into the collapses.

2. Dramatic Production - Images & Music, Not Technical

It is a different video than the 2 hour 1990 PBS production I saw which was very technical. It may have mentioned the earlier one you link to and referred to it as a "public relations" piece rather than a documentary on the construction.

Thoughtful of you to post the links. THX
